This 1969 Ford Mustang Boss 429 was built on March 19, 1969, and delivered new to Foss Motors of Etna, Pennsylvania. The car is finished in Wimbledon White over black vinyl and powered by a 429ci Boss V8 paired with a four-speed close-ratio manual transmission. Factory equipment includes a Competition Suspension, Holley four-barrel carburetor, power front disc brakes, the Drag Pack, power steering, a 3.91 Traction-Lok rear axle, a push-button AM radio, and a trunk-mounted battery. The car is said to have remained in the seller’s family since the 1977 and was acquired by the seller in 2019 and subsequently refurbished. This Boss 429 is offered with a removed set of wheels, an Elite Marti Report, and a Pennsylvania title in the seller’s name.

The SportsRoof body was reportedly refinished in the factory Wimbledon White (M) in 2019. Features include a hood scoop, front spoiler, body-colored sport mirrors, driving lamps, quarter panel scoops, chrome bumpers, Boss 429 badging on the fenders, reverse lights, and a dual-outlet exhaust that exits below the rear bumper.

Chrome 15″ Magnum 500 wheels wear Mustang-emblem center caps and are mounted with F60-15 Goodyear Polyglas GT white-letter tires. A space-saver spare wheel, tire, and jack are mounted in the trunk. Features include power steering, Competition Suspension with front and rear anti-roll bars, and the Drag Pack. Braking is handled by power-assisted front discs and rear drums.

The cabin features high-back bucket front seats trimmed in black vinyl with knit inserts and matching door trim panels. Equipment includes a center console, Hurst shifter with wood grip, Philco push-button AM radio, an electric clock, wood trim accents, deluxe lap belts, polished door sills, and a heater/defroster.

The wood three-spoke steering wheel frames a 120-mph speedometer, 8k-rpm tachometer, and gauges for fuel level and coolant temperature. The five-digit mechanical odometer shows 55k miles, a handful of which were added by the seller.

Kar Kraft of Dearborn, Michigan was commissioned by Ford to modify Cobra Jet Mustangs with a larger 429ci V8 featuring “crescent” shaped combustion chambers. Aluminum dry-deck cylinder heads are fitted along with an aluminum intake manifold and a four-barrel Holley 735-cfm carburetor. The engine came from the factory with a forged steel crankshaft, forged connecting rods, and solid lifters. The engine is said to have suffered a cracked cylinder head during previous ownership and was rebuilt during current ownership.

A photo of the engine stamp shows number 172986, which matches the last six digits of the vehicle’s VIN. A photo of the transmission stamping is provided within the gallery.

Power is sent to the rear wheels through a four-speed close-ratio manual transmission and a 3.91 Traction-Lok nine-inch rear axle. A selection of part stamping images and part packaging used during the refurbishment are shown in the gallery.

The Elite Marti report details the original colors and equipment and lists a March 19, 1969 build date.

The Pennsylvania title lists a “Classic Vehicle” brand.
