This 1969 Ford Mustang Boss 429 is one of approximately 850 examples produced for the model year and was built on May 13, 1969.
The engine was overhauled in 2005 by GRC Performance, and additional work involved removing the emission control equipment, rebuilding the transmission, and repainting the body.
The car is finished in red over black Clarion Knit vinyl upholstery, and power is from a 429ci V8 mated to a close-ratio four-speed manual transmission and a Traction-Lok differential.
Additional factory equipment includes a front spoiler, power-assisted front disc brakes, power steering, competition suspension, a trunk-mounted battery, color-keyed racing mirrors, a Philco AM radio, a center console, and the Visibility and Interior Decor-Deluxe groups.
The Boss 429 was offered for the 1969 and 1970 model years in order to homologate the 429 engine for use in NASCAR.
Production was completed by Kar Kraft and each example was given a serialized number.
Originally finished in red, this example was assigned serial number KK1791 and have been repainted.
Features include a hood scoop, front spoiler, louvered back glass cover, Boss 429 badging on the fenders, chrome bumpers, body-color sport mirrors, quarter panel scoops, reverse lights, and a dual-outlet exhaust that exits below the rear bumper.
Chrome 15″ Magnum 500 wheels are mounted with raised-letter 235/60 Cooper Cobra tires.
The Boss 429 model was equipped with revised control arms, a higher-rate front anti-roll bar than other Mustangs, a rear anti-roll bar, and staggered rear shock absorbers.
Power-assisted brakes with discs up front and drums out back were standard on the 429, with the front brakes reinforced with heavy-duty hubs and rotors as well as oversized spindles.
Power-assisted steering was also equipped from the factory.
The cabin features high-back bucket seats trimmed in black Clarion Knit vinyl along with a matching rear bench, color-keyed carpets, and simulated woodgrain accents on the dash, console, and deluxe door panels.
The car was optioned with the Interior Decor Group–Deluxe and Visibility Group packages, and it features a Philco AM radio, a dash-mounted rally clock, deluxe seat belts, and courtesy lights for the glovebox, ashtray, and trunk.
The woodgrain-rimmed steering wheel frames a 120-mph speedometer, an 8k-rpm tachometer, and gauges for coolant temperature and fuel level.
Controls for the choke and hood scoop are located on a steel bracket mounted on the lower dash area above the accelerator pedal.
The five-digit odometer shows 32k miles, total mileage is unknown.
