Who Built the Cobra Replicas? 120 Companies, 16 Countries

This article answers one question: which companies have ever built a Shelby Cobra replica, kit, tribute, or continuation car? I set out expecting to find perhaps forty. I found roughly 120, across sixteen countries and five decades, and I am confident the list is still incomplete.

The full roster lives on a separate page, because it is a reference document rather than a story, and because it will keep changing as people correct it. What follows is what the research actually turned up. Where these cars came from, which companies became which other companies, and why so much of this record survives in conversation rather than in any archive.

Two things this article is not. It does not estimate how many cars were built, which is a different question and a harder one. It does not rank the companies. Every entry on the roster carries a mark showing how well I could confirm it, and fewer than half of the 120 are solidly documented.

I have no commercial relationship with any manufacturer named here, other than the fact that I currently own an ERA 427 S/C Shelby Cobra. Nobody paid for a mention, and nobody was left out for declining to.

Why this list is harder to build than it sounds

The absence of a good Cobra builder list is not an oversight. The market has been very dynamic over several decades, and four items account for much of the difficulty in assembling this list.

There is no central registry. Original Cobras have the SAAC World Registry, while replicas have no equivalent, so no organization has ever had a reason to maintain a builder roster.
The market ran on small shops. People have built Cobra replicas since the 1970s, and much of that work came from small fiberglass operations that never advertised outside a regional car club.
Companies moved, renamed, and changed hands. Shell Valley, for example, has passed through three owners, and Hurricane was founded in Lee’s Summit, Missouri, before relocating to Lake City, Iowa. Everett-Morrison moved from Tampa to Baytown, Texas, around 2008, and most sources still list Florida.
When a builder closed, its record closed with it. No archives captured the paperwork, and in several cases the company name is all that survives.

The implication matters for how you read what follows, because any list of Cobra builders is a snapshot of what survives in public sources rather than a census. This one is labeled accordingly.

How the roster is marked

Each entry carries one of five marks.

✅ Confirmed — corroborated across independent sources.
🟡 Partial — the company and its identity are confirmed, but details remain unresolved.
📓 Community-documented — recorded firsthand by a named person in a club, forum, or registry, but not corroborated in documentary sources.
⚪ Unverified — the name is established in the market, but I could not confirm dates, location, or status.
❓ No record found — researched directly, and no reliable source turned up.

The third mark is new, and I added it partway through for reasons the rest of this article explains.

A note on terms, since there are four in play. A replica is a car built to resemble a Cobra by a company with no connection to the original. A kit is one form a replica takes, sold as components for the buyer or a shop to assemble. A tribute is the same thing under a softer name, preferred by some builders. A continuation is different in kind, built under license with lineage to the original AC and Shelby operations, and in Shelby’s case carrying official CSX serial numbers. The roster covers all four.

One thing you will not find is production numbers. I ran two research passes at that question and most of the figures fail verification, so rather than print numbers I cannot confirm, I have left them out entirely. That question deserves its own article, and it will get one. The single exception is Superformance, which reports 3,000-plus MkIII Cobras and 6,500-plus cars across all models.

The first one

Every replica market has a first car, and this one traces to a man who had built the originals.

Steve Arntz worked with Carroll Shelby on the original Cobras. After Shelby stopped 427 production, Arntz acquired frames, body parts, and tooling, and began building cars in South San Francisco in the late 1970s. He did not simply copy what he had helped make. He replaced the original round-tube frame with a box frame. He also moved the engine roughly ten inches toward the rear axle, producing a weight distribution of about 56 percent rear and 44 percent front.

He bought his frames from Ron Butler, whom he knew from Shelby, where Butler had been a crew chief. When Arntz went bankrupt around 1980, Butler took over the operation and continued building into the 1990s.

So the first two companies in this market were founded by two men from inside Shelby’s own operation, building on Shelby’s own tooling, one supplying the other. That is the origin of the entire replica industry, and it appears in none of the published manufacturer lists I have seen.

Companies became other companies

The single most useful thing this research produced is not the count. It is the succession — who bought whom, what got renamed, and where the tooling went. If you are trying to identify a car, this is the part that matters. The name on the paperwork often belongs to a company that no longer exists under it.

Fiberfab to Street Beasts. Fiberfab was founded in 1964 by Warren Goodwin and built Cobra replicas among many other kits. Classic Motor Carriages of Miami acquired it in 1983. CMC was, by several accounts, the largest kit car operation in the country. In 1994 it was forced to close after the Florida Attorney General sued on behalf of roughly 900 customers, and it agreed to pay 2.5 million dollars in compensation. The operation continued under a new entity and later traded as Street Beasts, which closed in 2010 and auctioned its plant and molds the following year. Four company names, one chain, forty-six years.

Arntz to Butler, described above.

Midstates to Shell Valley, absorbed in 1999.

Lone Star Classics to Ultimate Classic Cars. Dennis Cahill bought a Lone Star LS-427 kit in 2015 and liked it enough to buy the company. He moved the tooling and staff to Boerne, Texas, where the car is now sold as the GT-427.

B&B to McGill. Barry McGill co-owned B&B Manufacturing with Bryan Anderson for about twenty years. They parted in late 2008 and McGill founded his own operation in Granby, Missouri, building a similar line.

L.R. Roadsters to Ram to Realm. This one resolved two entries at once. Adrian Cocking founded L.R. Roadsters in Chingford in 1984 under the brand name Ram, then moved to Newmarket in 1986. He traded as Ram Automotive from Cardiff and later Witham, and has operated as Realm Engineering at Honeybourne since 2000. The chassis was co-designed with the Formula One constructor Adrian Reynard. Ram and Realm are not two companies. They are one company under one man across four decades.

Dax onward. Dax began in 1968 as DJ Sportscars, a fiberglass moulding company in North Weald, Essex, and became the first British company to build a kit-based AC 427 Cobra replica. Production of the Dax 427 passed to John Kox in 2017.

The cars were built in more places than anyone lists

This was the largest surprise. The published manufacturer lists cover the United States and, occasionally, the United Kingdom. The actual geography is far wider.

Germany had a cottage industry. At least ten German firms built Cobra replicas, mostly in the 1980s and 1990s. They are Mohr, Saier, Cobra Kuhn, Phoenix, Stallion Cars, Classic-Car Janssen, Lorenz and Rankl, Lorico, RH Products, and Hülcher. Most rest on a single curated source and are marked accordingly, but the pattern is unmistakable and it is entirely absent from the English-language record.

Brazil had at least thirteen. ABC, Americar, Classic Car, Cobramotorsport, Garage AS, Garden Sound, Glaspac, HotSnake, Newtrack, Pantera, PMC, QSH, and WW Trevis. All thirteen come from one Brazilian reference work, which is one source no matter how many places repeat it, so they are marked as thin. Americar of Santo André completed its first Cobra in 2000. Cobramotorsport has been building since a 1991 factory.

Argentina has a live scene. Cobra Motorsport of Pilar builds a 302, a 427, and an AC Bristol style car. AC Coxx of Olivos builds an FIA-style car modeled on CSX 2260. Carkrafts builds complete cars in-house on a chromed tubular chassis.

And then the singles. Switzerland had Weinem and Künzli. Austria had Tomaszo. Spain had Replicas Vasko, and France had ACE. Estonia has Rexer. Indonesia had Marvia Graha in Jakarta. The Philippines had Michel Motorsport in Quezon City, from 1977. South Africa had Shamrock in Cape Town well before Hi-Tech became the country’s most widely known builder.

Sixteen countries. Any list that stops at the American builders is describing a fraction of what has happened.

One name, two companies

Three times in this research, two unrelated companies turned out to share a name. This is worth spelling out, because if you own one of these cars, the first fact about it may be ambiguous.

Hi-Tech. Hi-Tech Motorsports operated in Scottsdale, Arizona, under Tom D’Antonio, and is out of business. The shop ran three or four people and hand-laid its fiberglass bodies rather than using blown chopper-gun panels. Cars were built so that parts interchanged with original Shelby components, and a lower-cost version used a nine-inch live rear axle in place of independent rear suspension. Documented cars carry an HTR serial prefix. Hi-Tech Automotive operates in Port Elizabeth, South Africa, was founded by Jimmy Price, and is active. It is the contract manufacturer behind Superformance.

Python. Unique Autocraft of Harlow, Essex built a Cobra replica called the Python between 1981 and 1993, on a steel chassis with Jaguar suspension. Python of Melbourne, Australia has built Cobra replicas since 1979. Same model name, opposite hemispheres, no relationship.

Weineck and Weinem. Weineck builds extreme-engined Cobras in Bad Gandersheim, Germany. Weinem built kit cars in Horgen, Switzerland, from 1972. One letter apart, different countries, different eras.

If you are researching a car described only as a Hi-Tech or a Python, establishing which company is meant is the first question to answer. It is not a detail to sort out later.

The record is not lost. It is just not written down.

This is the finding I did not expect, and it changed how I did the research.

I had recorded Classic Roadsters Ltd of Fargo, North Dakota as a company whose history could not be recovered. That was wrong. The history exists, in detail, written from memory by Paul Mossberg, a keymaster of the MG TD Replica Car Club who maintains its registry. Gary Rutherford founded the company in 1979. Its first car was the Duchess, a VW-based MG TD. It later built a Cobra with a longer wheelbase and a longer passenger compartment than most kits of the period. Rutherford sold the company and reacquired the name in the early 1990s. He sold the replica division to Don Scott of Minnesota Classic Motorsports on 16 July 2003, after which it traded as Classic Roadsters II. The last Cobra kit went out in December 2007.

None of that is in a corporate archive. It is on a forum for a different marque entirely, written by someone who owned one of the cars.

The same thing happened with Shamrock Automotive of Cape Town. Its existence is documented because its founder, Les Hayden, posted that he started building Cobra replicas there in 1984.

I had been treating recollection as weaker than documentation. For this market that is backwards. Most of these companies were small enough that they generated almost no documentary record, and the people who worked on the cars are the record. That is why the roster now carries a mark for community-documented sources, naming the person and their standing rather than burying the claim or discarding it.

What is still missing

Three categories fall outside what public sources can reach, and they are the reason I expect this roster to keep growing.

Regional and one-off builders. Shops that never had a catalog, a website, or an advertisement leave nothing to find. Several decades of Cobra replicas came from exactly those shops, and the 1970s and early 1980s in the United States are the thinnest stretch of the whole record.
Body-only suppliers. Some companies sold shells that other builders finished, and they rarely appear as manufacturers in their own right.
Whole countries. Japan, Mexico, the Nordics, Ireland, Poland, and the Middle East returned nothing. That is a statement about my searching, not about those markets.

If you have facts on any of this, I would love to hear from you at roark@roarkpollock.com. Founding dates, closure dates, locations, ownership changes, serial conventions, a catalog, a photograph of a builder’s plate. Corrections to entries I have marked confirmed are equally welcome. Most useful of all are names missing entirely, because that is the failure I cannot detect on my own.

Why any of this matters

Who built the car is the first fact about a replica, and every other fact depends on it. Serial conventions, chassis design, body construction, suspension geometry, and parts interchange all follow from the manufacturer. An owner who cannot establish which company built their car cannot establish much else about it either.

For a market this large, that record should not depend on whether the right person happens to still be posting on a forum.

A car documented once is trusted as long as it survives its owners. The same is true of the companies that built them.

The full roster of all 120 companies, with confidence marks, locations, dates, and succession, is here.

Frequently asked questions

Who manufactures Shelby Cobra replicas? Roughly 120 companies have built Shelby Cobra replicas since the 1970s, across sixteen countries. Those are the United States, Canada, the United Kingdom, Germany, Switzerland, Austria, Spain, Estonia, France, South Africa, Australia, New Zealand, Brazil, Argentina, Indonesia, and the Philippines. Companies currently producing in North America include Kirkham Motorsports, Superformance, ERA Replica Automobiles, and Factory Five Racing. So do Backdraft Racing, Unique Motorcars, Shell Valley Classic Wheels, Hurricane Roadsters, Everett-Morrison Motorcars, B&B Manufacturing, McGill Manufacturing, and Ultimate Classic Cars. A separate group of five companies builds Cobras under license or with direct AC and Shelby lineage.

Who built the first Cobra replica? Steve Arntz, of South San Francisco, California, is generally identified as the first. He had worked with Carroll Shelby on the original Cobras. After Shelby stopped 427 production, he acquired frames and body tooling and began building his own cars in the late 1970s. He replaced the original round-tube frame with a box frame and moved the engine roughly ten inches rearward. Arntz went bankrupt around 1980, and Ron Butler, a former Shelby crew chief who had supplied Arntz’s frames, took over the operation.

Are Shelby continuation Cobras the same as replicas? No. Continuation Cobras are built under license by Shelby American and carry official CSX serial numbers in dedicated blocks. CSX4000 covers the 427 S/C, CSX6000 the coil-over 427, CSX7000 the 289 FIA, CSX8000 the 289 slabside street car, and CSX9000 the Daytona Coupe. Replicas are built by independent manufacturers without that lineage. The distinction is legal and documentary rather than a judgment about how the cars are made.

Who actually builds Superformance and Backdraft Cobras? They are built by two different South African companies. Superformance is a Shelby-licensed brand and distributor whose cars are manufactured by Hi-Tech Automotive in Port Elizabeth, and whose chassis receive official CSX serial numbers. Backdraft Racing, headquartered in Boynton Beach, Florida, has its rolling chassis built by TR-Tec in Durban and installs the drivetrain in Florida. Note also that Hi-Tech Automotive of South Africa is unrelated to Hi-Tech Motorsports, a Cobra builder that operated in Scottsdale, Arizona under Tom D’Antonio and is no longer in business.

What is the difference between a Cobra kit, a roller, and a turnkey car? A kit is a component package the buyer assembles or pays someone to assemble, typically supplying the engine, transmission, and often the donor suspension parts. A roller is a rolling chassis delivered with body, suspension, and brakes but no engine or transmission, so the buyer or a shop installs the drivetrain. A turnkey car is delivered complete and running. The same manufacturer often offers more than one of these, and the format affects how a car is titled and documented.

How can I find out which company built my Cobra replica? Start with the serial or VIN pattern, since several manufacturers used identifiable conventions. Shelby continuation cars use CSX blocks and ERA uses a three-digit scheme. Contemporary used CCX serials, Backdraft stamps a BDR number separate from the VIN, and Hi-Tech Motorsports cars carry an HTR prefix. Next, look for a builder’s plate, the original kit invoice, or registration paperwork from the first titling. Chassis construction is also diagnostic, since Factory Five built its own tube chassis around Mustang donor parts while others used different designs. Bear in mind that the company named on your paperwork may have been bought, renamed, or absorbed. Where paperwork is missing, marque specialists and club registrars can often identify a builder from chassis and body characteristics.

Sources and method

This roster was assembled from four research passes across 2026. The first two were conducted by me. The last two were independent deep-research runs given the same brief on two different platforms, then reconciled against each other, with disagreements recorded rather than resolved silently.

That reconciliation matters for how much weight to put on any single entry. Two research runs agreeing is only meaningful when they reached the conclusion through different sources. A large share of the European and Brazilian entries in both runs trace back to the same underlying reference works. That makes them one source rather than two, and they are marked accordingly.

Where sources conflict, both readings are recorded on the roster rather than one being chosen quietly. Shell Valley’s founding year, Autokraft’s starting date, and the spelling of Southern Roadcraft’s founders all remain unsettled.

Three named authorities carry real weight here. Steve Hole is the marque historian behind A-Z of Kit Cars and totalkitcar.com. Paul Mossberg is registrar of the MG TD Replica Car Club, and Les Hayden founded Shamrock Automotive. Full source URLs for every entry appear on the roster page.
