1969 Mustang Boss 429 KK 1663

Acquired November 29, 2017


This magnificent 1969 Ford Mustang Boss 429 was the recipient of the highest award conferred by the Mustang Club of America, the Thoroughbred Gold Award. Thoroughbred Gold is awarded only to Mustangs determined through a strict judging regime to be 100-percent date-code correct. To achieve this exceptional standard of excellence, the recipient must be proven to use only original or NOS parts and components throughout, with zero exceptions. This includes not only the original drivetrain but also every single piece down to the most seemingly insignificant detail. In judging a vehicle for Thoroughbred Gold, MCA judges examine every single number on every single component for correctness and authenticity. This rigorous examination includes such items as the air filter, engine bay decals and undercarriage markings, labels and tags, console lid, Ram Air rubber hood seal—even the Comfort Weave seat upholstery, where used, is checked for correctness. Only 40-year-old original or Ford Motor Company NOS parts are accepted.

Those standards were met across the board in the Concours-grade restoration of this 1969 Boss 429. Kar Kraft number 1663, it was produced on April 1, 1969 and sold new at the legendary Tasca Ford in East Providence, Rhode Island. As New England’s most successful Ford dealer with access to Ford President Bunkie Knudsen’s inner sanctum, Tasca was instrumental to the creation of many performance Mustangs, including the Boss 429.

Restored in the original Candyapple Red paint with a black interior and equipped with the 820-T version of the Boss 429/375 HP engine, this Boss Nine is fitted with significant and hard to find components such as an original exhaust system, original tires and original battery. Furthermore, this ultimate award-winning Mustang Boss 429 is well-documented with the build sheet, owner’s card, Marti Report, copies of shipping invoices and owner’s manual with Boss 429 supplement.

The Boss Nine’s primary mission was the homologation of the new “Semi Hemi” 429 CI engine for NASCAR, but it was more than just a Mustang with a big engine. Every Boss 429 was treated to a Borg Warner close-ratio 4-speed, 3.91:1 Traction-Lok differential, power steering and front disc brakes, competition suspension with a ¾-inch rear sway bar, a trunk-mounted battery, chromed Magnum 500 wheels with F60-15 Goodyear Polyglas GT tires and the Deluxe Decor interior.
