Rear discs
Can someone please send me a pic of the rear brake pads form an 88 IROC. The ones that are already on my car look nothing like the ones the guys a schucks gave me.

Are your calipers cast iron or aluminum?
If they're aluminum, go back and ask for the pads for a 90. If they're cast iron, go back and ask for the ones for a 87. That will get you the right ones.

Thanks for the help. How would I tell if I have aluminum or cast iron calipers. The only RPO code I found that was brake related was "J65: BRAKE SYSTEM, PWR, FRT & RR DISC." Is there a code I am missing?
I should have thought of that Thanks

You should see the difference....the aluminum calipers are finned and should have "PBR" cast in them. The iron calipers look very close to the front ones.
