Every time I'm in the junkyard, I look for an A-body car with disc brakes. The inventory turns over quickly and there are never any cars like my72 GS. But sometimes there are some late 70's early 80's GM cars there with disc setups. For example there was a 78 LeSabre, a 72 Camaro, 78 camaro, 78 nova... most of these cars were gutted, but still had the disc setups. What cars should I be looking for, for the parts that will interchange to my 72?
