This 1970 Mustang Boss 429 is finished in yellow over black upholstery and was initially delivered to Don Seelye Ford of Kalamazoo, Michigan.

Power comes from a numbers-matching 429ci Boss V8 equipped with a four-barrel Holley carburetor mated to a four-speed close-ratio manual transmission and 3.91 Traction-Lok rear axle.

Equipment includes 15″ Magnum 500 wheels, power-assisted front disc brakes, power steering, the Drag Pack, the Competition Suspension Package, front and rear spoilers, and rear window louvers as well as a Rim Blow steering wheel, Hurst shifter, and a tachometer.

The car have been refurbished in the 1990s with work including repainting the body and rebuilding the engine and drivetrain.

The Boss 429 was offered for the 1969 and 1970 model years in order to homologate the 429 engine for use in NASCAR.

This example left the factory finished in Grabber Orange before reportedly being stripped to bare metal and repainted in its current shade of yellow in the 1990s.

Equipment includes a matte-black hood scoop, front and rear spoilers, rear window louvers, color-keyed mirror housings, reverse lamps, and chrome bumpers.

The 15″ Magnum 500 wheels feature Mustang logo center emblems and wear Goodyear Eagle tires.

Factory equipment includes power steering, power-assisted front disc brakes, the Competition Suspension package, and Drag Pack equipment.

A space-saver spare wheel is mounted in the trunk.

The cabin features high-back bucket seats upholstered in black vinyl with knitted inserts.

Additional equipment includes a center console, Hurst shifter, an electric clock, a push-button AM radio, rubber floor mats, and woodgrain trim lining the door panels, dashboard, and center console.

The Rim-Blow steering wheel fronts a 120-mph speedometer, an 8k-rpm tachometer, and gauges for coolant temperature and fuel level.

The five-digit odometer shows under 56k miles.
