The wheelbase on Charlie Allens Dart is stretched slightly. The rear wheel openings are nearly stock, and the front spring location is due to specially made front springs that were to allow exactly 4 inches of lift before the front wheels pulled off the ground.
Charlies Dart had a fiberglass body, doors, fenders, hood, and bumpers. His car was purpose built from one end to the other. It also had a Corvair front steering assembly.
