Ok guys, got a parts question. I have some Zimmerman rotors for my '86 5kcstq, and I was wondering if they would fit on my '90 V8q. I don't have part numbers for either, but figuring that the rear of the quattros didn't seem to change that much, so I was going to guess that they would. Someone please let me know otherwise. Joel '90 V8q '86 5kcstq
