I just got my two Boss 302 kits today. It is reworked from the Mach 1 kit. The interior is untouched. The body is pretty much untouched other than filling in the holes for the side scoops. The intentions for the c pillar emblems are still present and would need to be filled in for the Boss 302 but are used on all other versions. The rear panel has the exhaust cut outs filled in and the hood is filled in. The hood pins were also removed from the hood and should have stayed. The new grill has an astrick in the directions indicating a chromed part but it is not chromed. The tail pipes have been corrected with turn downs and the engine is real nice. I love what I see and can't wait to build one!
