The Challengers Had the textured paint on the fillers the 74 I had had been painted over in body color and when I removed the paint the silver texture was underneth(I believe they were the color of the tail panel, weather it be black or silver.

my 74 also was ab5, interior too, yet it wasn't a metallic B5, the door panels were really nice just needed dyed to get the consistancy back, I think it'd been garage kept though.

NICE work on a very nice car, I like the later models too.
