I have a '90 Iroc that got into a fender bender here @ work. I need to find a replacement spoiler for the left (drivers) side fender. All of the spoilers I have seen thus far in the area are slightly shorter & narrower than mine. Granted, none of the cars I've found thus far have been a '90 Iroc either. Is there a difference somewhere?
I dont want to have to replace the whole spoiler if at all possible.

I believe 90-92 had their own style of ground effects.

Does anyone know of an aftermarket source or other option for replacing this single piece? Have looked everywhere local and am running out of places on computer to look for used parts.

You ask for a spoiler, then some responded about a ground effect, so I'm wondering which you are in need of.

As for Camaro "RS style" spoilers, there are 2. One short, 1 tall. Either will fti, its just a matter of all 3 pieces matching each other.

I am looking to replace a broken spoiler section on the left (drivers) side of a '90 Iroc. The spoiler is larger than any I've found locally. It measures 4 3/4" across the top face from front of spoiler to the rear.

How tall is it, bottom to top, on the back "wall"? There is always the possibility of yours being the aftermarket version, of the extra tall style.

You need to get a spoiler section from an 87-90 Camaro. The 82-86/91-92 spoilers are a little smaller because they didn't have the third brake light in the spoiler.
