1967 Ford Mustang GTA 289 K-Code

This 1967 Ford Mustang GTA convertible isn’t just another K-code — Marti Report data confirms it’s one of the last 289 High-Performance convertibles built at Ford’s San Jose plant, and one of only 16 built with an automatic transmission. Finished in a rare Lime Gold over a white top, it packs 271 horsepower, factory disc brakes, and the same high-rpm hardware Ford gave cars built to be raced. V8TV walks through why this Brothers Collection Mustang matters to K-code collectors. Watch to see what made it one of just 50.

Most 1967 Mustangs get lumped into a single, familiar story — fastback, big engine, GT stripes. This one breaks from the script in almost every way that matters, starting with the fact it left the San Jose assembly plant as one of the very last of its kind, wearing a color most people have never seen on a Mustang before or since, and carrying a Marti Report that backs up a production number small enough to make most K-code collectors stop scrolling.

The Last of the 289 K-Codes

Ford’s Marti Report — the industry-standard way to verify a vintage Mustang’s original build sheet — confirms this convertible as one of the final 289 High-Performance K-code cars built at Ford’s San Jose assembly plant before that line moved on to other configurations. That last-of-its-kind status matters more to serious collectors than horsepower alone, since it places this particular car at the tail end of a production run that Ford itself treated as a closing chapter for the 289 K-code option in convertible form.

Only One of Sixteen

Ford built just 50 examples of the 289 K-code convertible for 1967, and of those, only 16 left the factory with an automatic transmission rather than a four-speed manual. That makes this car, an automatic, a subset within an already tiny production number — rare inside rare. For collectors chasing documented originality rather than just badge appeal, that kind of nested rarity is exactly what separates a genuinely significant survivor from a Mustang that merely wears the right emblems.

Lime Gold Over White: A Color Most Collectors Never See

The paint alone sets this car apart from the sea of red and black 1967 Mustangs that dominate most car shows. Finished in Lime Gold with a white convertible top, it’s a color combination few buyers chose new and even fewer examples have survived wearing today. V8TV’s walkaround lingers on that paint deliberately, treating it as one more piece of evidence that this isn’t a generic restoration painted whatever shade happened to be popular, but a car presented the way it left the factory.

271 Horsepower Wasn’t the Whole Story

The 289 cubic inch High-Performance V8 under the hood made 271 horsepower and 312 lb-ft of torque on paper, numbers that read modestly by later muscle car standards but undersell what the K-code package actually delivered. Ford paired the engine with a larger carburetor, a high-rpm fuel pump, upgraded suspension, and factory disc brakes — a full performance package built around the engine rather than a single spec bump. Those supporting upgrades are what turned a 289 into a genuine performance option rather than just a bigger number on a window sticker.

Built to Race From the Factory Floor

Ford knew exactly what buyers would do with a K-code Mustang, and the paperwork proved it: the company offered a shorter factory warranty on these cars, anticipating they would be pushed harder and more often than a standard 289 model. Lightweight construction combined with the upgraded internals — stronger bearings and pistons built to handle sustained high RPM — made the K-code a legitimate stoplight racing champion in period, not just a car that looked fast sitting still.

From the Brothers Collection

This particular example comes out of what one commenter identifies as the Brothers Collection, a detail that carries weight among Mustang collectors who track provenance as closely as they track build sheets. A documented ownership history, paired with Marti Report verification, is what turns a nice-looking convertible into a car serious buyers will pay a premium for — the paper trail is often worth as much as the sheet metal itself when it comes to K-code values.

Why the Top Stayed Up

Not every question gets answered in a five-minute walkaround. One viewer wanted to know why the convertible top stayed up for most of the segment on a car built specifically to be driven with it down — a fair question about a car this rare, and one the video leaves for viewers to puzzle over rather than explain on camera. Small unresolved details like that are part of what keeps a comment section active days and years after a video first goes up.

What Makes a K-Code Worth Chasing

Ford’s 289 High-Performance engine earned the K-code designation for a reason — a solid-lifter valvetrain, better-breathing heads, and a factory tune aimed squarely at drivers who wanted more than a Mustang’s base V8 could offer. Combine that engine with convertible-only production numbers this small, and you get exactly the kind of car Marti Report verification exists for: a way to prove, on paper, that a survivor like this one really is as rare as its story suggests, rather than just another 289 Mustang wearing an unverified K-code badge.

A Weekly Series Built to Find Cars Like This

V8TV built its Muscle Car of the Week format around exactly this kind of car — not the most famous or the fastest example of its model, but the one with a story and a paper trail worth slowing down for. A 1967 K-code convertible with San Jose production history, Marti verification, and documented collection ownership is precisely the caliber of find the series exists to showcase, one weekly episode at a time, and precisely why fans of the format keep coming back for the next one.

A Convertible That Rewrites the Usual ’67 Mustang Story

Walk into most car shows and the 1967 Mustangs on display tell an interchangeable story: a fastback, a big-block swap, GT badging bolted on after the fact. This car does the opposite work, using documentation instead of modification to make its case — a factory K-code convertible, verified against Ford’s own records, wearing a color nobody replicates just for show-car points. That’s a harder story to fake than horsepower, and it’s exactly why V8TV chose to feature it as one of its weekly picks. That combination of paperwork and presentation is why K-code convertibles like this one keep climbing in value while lesser-documented Mustangs stay flat.
