To legions of Ford fans, nothing compares to the mighty Boss 429 Mustang. Designed and built at the height of Ford Motor Company’s all-out Total Performance campaign, it had just one purpose—to qualify Ford’s new Hemi-head Boss 429 engine for NASCAR competition. To create the “Boss Nine,” the cars were essentially hand-built by Ford racing subcontractor Kar Kraft of Brighton, Michigan, with extensive modifications to the Mustang’s basic structure. A complete package, the Boss 429 Mustang was loaded with special high-performance features. Among them was a Toploader close-ratio 4-speed transmission, a 9-inch Traction-Lok rear end with 3.91 gears, an engine-oil cooler, a trunk-mounted battery, competition suspension with front and rear anti-roll bars and staggered rear shocks, power front disc and rear drum brakes, chrome Magnum 500 wheels and F60x15 belted raised-white-letter tires. A large cold-air scoop atop the long Mustang hood, “Boss 429” decals at each front fender and a menacing stance were the only external clues. Laughably, Ford rated the “street” Boss 429 at 375 HP, well below its true output. Listed from $4,087 new, the Boss 429 Mustang was the priciest non-Shelby Mustang offered. Production of 859 (including two Boss Cougars) for 1969 was followed by 499 or 500 more, depending on the source, for 1970. Numbered KK 2029, this 1969 Ford Mustang Boss 429 is one of just 859 examples produced for the 1969 model year. Benefiting from a three-year comprehensive restoration, it of course features the Boss 429 CI V-8 engine and a 4-speed close-ratio manual transmission. Finished in Candyapple Red over black Clarion knit/vinyl bucket seats, the Boss is highly equipped with a console and the Visibility and Interior Decor groups, plus wood-grain interior trim, a rim-blow steering wheel, Philco AM radio, Deluxe belts with warning light, color-keyed racing mirrors with driver’s side remote, a front air spoiler, trunk-mounted battery and power steering. Other highlights include a 3.91:1 Traction-Lok rear axle, Competition suspension, power front disc brakes and Goodyear Polyglas GT White-letter tires. The restoration also features correct factory chalk markings. Documented by a Deluxe Marti Report, original window sticker, three original build sheets, and restoration receipts, this Boss is, simply put, a collector-grade legend.
