1966 Ford Mustang GT K Code HiPo Convertible 271 HP next Convertible – ONE OF ONLY 87 DOCUMENTED IN K-CODE REGISTRY ONLY 4% OF K-CODE CONVERTIBLES MADE IN ‘66 WERE TRUE GT’s Authentic K code listed in the K-Code Registry and authentic, original documented GT I have received many offers for this car, and have considered sending it to Barrett Jackson in Scottsdale, AZ. However, I am leery to invest a couple of thousand dollars in detail work and transport it down to Arizona for a no-reserve auction where I have had mixed results in the past. I have decided to list it with the ridiculously low start price of $34,999.99 with no reserve and will let the chips fall where they may. Before you is one of the most sought after Mustangs ever produced. A Genuine, factory original, 1966 Factory GT equipped, ORIGINAL matching numbers 289c.i. V-8/271 HP HiPo "K Code" convertible, with factory 4 speed transmission and finished in Vintage Burgundy with black interior. According to the K-Code Registry, only 87 (eighty-seven) 1966 K Code convertibles are known to still exist, out of less than 1,000 convertible K Code cars produced. There were only 5,469 K codes produced in 1966, with many more of the coupes and fastbacks built than convertibles. In fact, there were many less K code convertibles built in ’66 than Shelby Cobra GT-350’s! Ford production records show that less than 4% (Four percent!) of the ultra-rare K Codes were equipped with the P-10 designated GT Package from the factory. What is so special about a K Code GT? The K Code is legendary on its own, being the same equipment and engine that Carroll Shelby based the 65/66 GT-350 cars on. And I don't need to tell you what those sell for these days. And, unless you are one of the lucky 4 people to get an original 66 GT-350 convertible, a Mustang K Code convert is as close to a GT-350 convertible you can get. The GT Package also had some serious hardware , namely, a 22:1 quick ratio steering box, disc brakes, heavy duty suspension, springs, shocks and sway bars, GT ornamentation, fog lights, trumpeted dual exhaust, and more. This particular "K Kar" is truly spectacular and among the best driver examples you will find.. It is a true ORIGINAL MATCHING NUMBERS car, which is different from a regular matching numbers car in that the engine, transmission, etc. are stamped for THIS car and have been in THIS CAR SINCE NEW, instead of simply being period-correct replacements. It has spent the last 30 years in a private collection. The body is nearly flawless, with original sheet metal panels, and rust free. All proper original K Code items are present and accounted for, another rarity. The optional 8,000 RPM Rally Pac gauges are original and mint – and still operational! Interior is beautiful, with seats and dash in excellent condition and with the original factory-installed center console. Carpet has a little fade but is in great condition for its age and is original. It can either be dyed or replaced; the former (or leaving it as-is) being optimal for the purist. The undercarriage is very clean for a driver and was restored a decade or so ago. Engine and trunk compartments are clean and well-detailed. More importantly, the factory original door data tag and VIN plate is affixed to the driver’s door where it was put at the factory 40+ years ago. It has never been removed, swapped to another door, or replaced with a reproduction tag to disguise this car as something it is not - unlike most other claimed "correct" K Code cars! Additionally, this car still has its original body buck tag documenting the car and its options, including the code P10 - for GT Equipment, as well as the special designation for the rare 8-track radio with factory door speakers (which sounds great and is factory original). The fender stamp on the passenger side that is obscured by the fender lip carries the same K-code VIN number as the opposite stamped VIN, door tag and buck tag. The recipient of a thorough mechanical and cosmetic restoration some years ago, this little Pony still looks excellent. Better still, it starts, runs, drives, and performs excellently in all respects. Never has a real K Code motor sounded better than when in a 65-66 Convertible! The solid lifter symphony mixed with the Chris Craft-like burble of correct dual exhaust exiting through GT turn-down tips is the stuff dreams are made of. Pulling clean and strong through all 4 gears, and putting the power down through the correct 3.89:1 geared 9" rear end, this little car will run with the big boys. Docile as needed and mean when wanted. The car has been recently serviced and everything is ready to go. The only item that may need addressing is the emergency brake should be replaced, which is common for older Mustangs. If you have lusted after a real K Convert that you can drive but just haven't found the right one yet, your wait is over! The Decoded Vehicle Identification Plate on the driver’s door is again unaltered and is the original plate that matches the casting number on the engine block and the VIN stamped under the hood, as well as the original buck tag.

AXLE TRANS Bottom of Form As mentioned earlier, this car also has its original buck tag, which is mounted under the hood on the driver’s side next to the stamped VIN# on the driver’s side under the hood. Buck tags were used in only one plant during 1964½ -1966 Mustang production - Metuchen, NJ (where this car is from). In 1967, Dearborn, MI also started using the buck tag system, and in late 1969 San Jose did as well. This is one reason why buck tags are only mounted on a small portion of Mustangs from ’64½-’66, as well as the fact many have been discarded over the years. The buck tag’s purpose was to notify line workers that some hole or modification needed to happen during assembly on the shell or sheet metal. Some codes as of yet remain to be decoded. The buck tag reads as follows: 1st Line: D – Dealer Order 304 – Rotation Number 2nd Line: 5 – Welding Bay # G8 – Build Date (July 8, 1966) 6T08K267831 – Vehicle Identification Number (VIN#) 3rd Line: 76A – Mustang Convertible R – Color (Original color of the car was Ivy Green Metallic) 26 - Standard Black Interior 4th Line: 4 Speed – 4 Speed Transmission Stereo – Special Order Stereo P10 – Documented GT Car 5th Line: Top-B Clear – Black Top, Manual, Plastic Rear Window The casting numbers on the block, which are pictured, can be decoded as follows: 6D18 – Block was cast on April 18, 1966 0 C5AE-6015E – Correct code for a 1966 K-Code Mustang (C-1960’s, 5-1965, A-Generic Full-Size Ford, E-Engine, 6015-Engine Base Assembly Part #, E-Engineering Version) The tag on the transmission, which is also pictured, is decoded as follows: HEH BX – 1966 289 HiPo K-Code/GT-350 Close Ratio 4 Speed Toploader Transmission 012607 – S/N of the transmission unit (In order of tagging; has nothing to do with S/N of vehicle) You will be immediately impressed how evenly the car has aged unlike many of the cars out there. This truly is a K-code that you can begin enjoying immediately without having to address any issues. Buyers of the GT Equipment Package could add the K-code to their new ride for an extra $276 back in 1965. The cost to add this engine to new Mustangs without the GT package was $328. The “K” represented the engine code on the VIN number of these Mustangs. The K-Code engine was first introduced by Ford in 1963, and was featured in cars such as the Fairlane and the Comet. Each K-Code Mustang had a special badge on their front fenders that read “HIGH PERFORMANCE 289”. No doubt about it, the K-Code Mustang was all performance. In fact, K-Code Mustangs were not available with air conditioning or power steering. And you couldn’t buy one with an automatic transmission until the 1966 model year. Prior to that K-Code Mustangs were 4-speed only. The car also came with a shorter warranty than the typical Mustang. K-Code buyers were looking at a 3 month or 4,000 mile warranty instead of the standard 12 month or 12,000 miles plan. I guess the folks at Ford figured most people who purchased the car would put it through its paces on a daily basis, and they were probably right. People often ask how the K-Code engine was different from the other D,C, and A code 289 engines featured in 1965-1967 Mustangs. Well, once again, think performance. For starters, this engine featured upgraded pistons, cylinder heads, carburetor, solid lifters, and connecting rods. In addition, one look under the hood and you’d notice the chrome air cleaner and valve covers. Oh, and we can’t forget the “289 High Performance” lettering atop the air cleaner and tags on the front fenders. With an estimated 271 hp at its disposal, it was easy to tell this car from other 289 powered Mustangs of the day. But wait, there’s more. The differences didn’t stop there. In fact, the entire driveline of these cars was designed for performance. We’re talking about a high-performance clutch, drive shaft, rear differential, and suspension. It’s no wonder Shelby put the engine in his racing performance GT350 Mustangs. In fact, the first Shelby Mustang, the Shelby GT350R featured a modified K-Code engine. These days collectors of the Ford Mustang look back fondly on the K-Code. As such, they are highly sought after. Unfortunately only a limited number of these engines were produced between 1963-1967, and even fewer K-code Mustangs (About 13,214). If you own one, you own a valued piece of history. If you want one, join the club.
