So i bought my 91, rs with front bumper damage which was un repairable, so throughout the long time i hav owned it i could only find a i rock bumper with the bowtie. I bought the bumper because it was in flawlesss cond. and only 20 bucks. My question is should i use the irock bumper on my RS or schould i find a way to cut out and remove the center and incert the Rs grill?? or may just leave it alone.......

 

Actually the bumpers are the same on an IROC and z28 and RS from 85-92. The only differences are the chin spoiler (aero vs. flat) and the grille. To answer your question yes you can use the IROC bumper and you can change out the grille or leave it if you decide you want to add foglights I haven't ever done this but from what I understand the holes are different so you would have to drill some hole. I have an RS and am looking for a IROC or Z28 grille so if you decide to change to your RS grille I would be interested in your Z28 grille. Hope this answers your question and maybe you could pay for your bumper.

 

And you don't have to cut anything - the grills are just held in with screws - the RS grills have screws in the top and bottom I believe, the "Camaro" grille has screws in the top and the inner sides, and the Bowtie grill I assume are the same as the "Camaro" grilles.

Under your RS grill, you will find holes for the install of foglights if you like. REAL Camaro foglights are anywhere from $50 a set used to well over $200 for "new unused stock". WalMart has el-cheapo fog lights that look very similar abd are about $20 a set - alot of us that have better things to spend cash on at the moment settle for these. You can hunt down a used foglight switch from ebay or local JY and use the stock switch - just run 12v+ to the stock switch and a ground, the let the switch run 12v+ out to under the hood to activate a relay, and wire the foglights with direct battery power though the relay - that way you aren't running high amps through the switch and don't have to worry about fuses and such.

This is what I've done with my 92 RS.
