Hey guys, I want to put the z28 gfx on my Berlinetta. preferably 91 92 bc of the cutouts in the gfx, but ive been told I have to change the nose as well. Is this true? Other than the gfx I dont see the difference in the car. Its my understanding 82 to 92 was the same thing, just had berlinetta rs iroc and z28 so where would the front nose change come into the picture?
