This 1969 Ford Mustang Boss 429 was delivered new to Ron’s Ford Sales of Bristol, Tennessee, and was acquired by the seller in Colorado in 2000. A 2018 refurbishment is said to have included refinishing the car in maroon over new black vinyl upholstery, and power comes from a replacement 429ci V8 mated to a four-speed manual transmission and a Traction-Lok differential. Additional equipment includes a functional hood scoop, 15″ Magnum 500 wheels, Goodyear Polyglas GT tires, front disc brakes, high-back front bucket seats, and a factory Philco AM radio. This Boss 429 is now offered with an Elite Marti Report, historical documentation, manufacturer’s literature, and a clean Colorado title in the seller’s name.
The Boss 429 was produced for the 1969-70 model years to homologate the 429 engine for use in NASCAR. Final assembly was performed by Kar Kraft Engineering of Brighton, Michigan, and this example received a unique “KK NASCAR 429” build number of 1444. The car was factory finished in Royal Maroon that was stripped and repainted during refurbishment in 2018. Exterior features include a front lip spoiler, a functional hood scoop, color-keyed side mirrors, and a rear spoiler. Detail images of the painted surfaces and body-panel gaps can be viewed in the gallery below.
Chrome-clad 15″ Magnum 500 wheels feature black pockets and are mounted with Goodyear Polyglas GT F60-15 tires. All Boss 429s came equipped with upgraded suspension components including revised control arms, a higher-rate front anti-roll bar than other Mustang variants, a rear anti-roll bar, and staggered rear shock absorbers. Power steering was fitted from the factory along with power-assisted front disc and rear drum brakes.
The cabin features Clarion Knit black vinyl upholstery with matching carpeting throughout as well as red seat-back accents and simulated woodgrain appliqués on the dashboard, center console, and door panels. The car was optioned with high-back front bucket seats, the Interior Decor Group—Deluxe and Visibility Group packages, and a factory Philco AM radio.
A woodgrain steering wheel frames instrumentation that includes a 120-mph speedometer, a tachometer, and auxiliary gauges. The five-digit odometer shows 41k miles; total mileage is unknown.
The replacement 429ci V8 features magnesium valve covers and aluminum cylinder heads with partially hemispherical combustion chambers and was factory rated at 375 horsepower and 450 lb-ft of torque.
Power is sent to the rear wheels through a four-speed manual transmission and a 3.91:1 ratio Traction-Lok differential. Additional underside images can be viewed in the gallery.
A framed window sticker and Elite Marti Report list standard and optional equipment and show delivery to Ron’s Ford Sales of Bristol, Tennessee, with a total price of $4935.26.
