This Mopar is in serious need of a sandblaster! Also, they'll go for a spin in one of the most famous Mopars of all time. Detroit Muscle goes on the hunt for Project Ultra Violet...a 1970 Challenger. The team salvages a rotted out '70 Challenger and shows how-to weld in a new metal roof, drip rails, and A-pillars. Chassis guru Jeff Schwartz brings in his G-Machine chassis to convert the uni-body Challenger to a full-frame. Then, the team grafts a low deck, all-aluminum Hemi, and T56 six-speed gearbox into the '70 Challenger resto-mod. Next, celebrity builder Chris Ryan shows how-to lay down metallic paint and graphics on the very purple Challenger and the team fabs a high flow EFI fuel system, serpentine belt drive, and dual-fan cooling system for '70 Hemi Challenger.
