One of the coolest displays at the Muscle Car and Corvette Nationals is the "Barn Finds & Hidden Gems" display, which showcases cars and trucks as they were discovered in their present and unrestored states.   In this video, we take a look at a 1969 Ford Mustang BOSS 429 that was reported to be raced many years ago, and was displayed along with its new engine and vintage 1967 Ford cab-over race car hauler.
