i have an 82 z28 im making into a race car, i need to replace some of the ground effects and i like the later 91-92 style better, is there any differance in the nose peices, or is it just the spoiler? also is there any differances in the rear bumper cover? thanks.

 

Both front and rear are different from the 82.

 

yep 82-84 were different in front and rear bumper covers from the 86+ years..

 

82-84, 85-90, and 91-92 85-92 are the same the only difference is screw locations for the ground effects to mount.
