Will ground effects off a 83z28 fit onto a 90 rs? I also am swapping front/back fender ro bumpers whatever they are called

 

They will bolt on. You might have to do a little adjusting on your mounting for the side gfx though.

That is a swap i don't see very often on here. just wondering... why are you putting the 83 gfx on your 90?

 

well origianlly the 83 was going to be my drag car but I have to go to college next year so it is on hold. I am about to paint my 90 and I wanted it to look NICE. Well the back bumper is crap because the guy that had it before me had a wreck and messed it up. There are rips in the frotn fender and the ground effects well I think they are a little different.it may just be the front back bumper but I dont' know for sure

 

This may stray from the topic a bit, but its sorta the same...

Will the nose and gfx off a 88-90 IROC fit onto an '83 Z28?

 

Yep, I've done it......in order for the 85-92 (Z28, RS, IROC-Z) nose to fit.....the plastic underneath the nose will have to be shaved back some (1982-1984 plastic beneath the nose).....if it's not shaved back....the 85-92 nose will not fit properly and will look like crap.....
