I have been wanting a 91-92 Z28 spoiler on my IROC...

However, I've seen the look of that spoiler and it looks funny to me w/o the rear bumper as well.

Whenever I get the spoiler, I'm going to look for a 91-92 rear bumper t go with it. My question is:

Are the two sides of the bumper (the extension things) the same from 85-92? Or do I need them from the donor 91-92?

Here's what I mean. Thanks to the owner for this pic.

 

No they r different and they actually have the bolt holes in different spots. I also thought that spoiler doesnt look right with out the bumper. At first i thought they were pretty close but when i got it home and tried it it was way off i should of took pix.MY dad is pretty good with fiber glass so 1 day when i was at work he molded them for me to fit the bumper. No1 has ever noticed it looks factory. If i ever redo the car again tho which i prob will 1 day ill most likely get the peices that goes with it and weld in the old holes and drill new.I also didnt like tho how the peices that go with it u have to drill a hole in the lip of the wheel well.

 

So should I just see if I can get the sides along with the rear bumper then?

 

yeh they might even let u have them see what u can do with them
