I'd like to know the differences in the gfx with camaros from different years. Also what years were there changes made? What were these changes? Are they all interchangeable?

 

well for one i know that on IROC's 1985-1987 the "IROC" decal on the doors were near the front of the door (closer to the front of the car) and 1988 and up the "IROC" decal on the door was on the rear of the door. also, on the stripe along the ground effects, the top one was black (this started in the 1988 year)...
