A Raven Black 1969 Ford Mustang Boss 429, built on 21 February 1969 and originally delivered to Hill & Sanders Ford in Wheaton, Maryland, carrying factory designation KK#1356. One of fewer than 900 first-year examples produced, it was fitted with the legendary 429 NASCAR-derived V-8, close-ratio four-speed Toploader, Traction-Lok rear axle, and full competition equipment. The original engine was removed in the late 1980s for a rebuild that was never completed, and the car has been in barn storage for over three decades. It now presents as a project vehicle accompanied by its original build sheet and a Deluxe Marti Report.
