84 Rear brakes

Hi new here I have an 84 trans am recaro edition it came with factory disc brakes I had to cut up my backing plate to get the calipers off so I could change everything to new and rebuild the rear axle I'm having a heck of a time finding them backing plates they hold the caliper I'm wondering is there any difference between the 84 rear brakes and the 89-92 rears

Welcome to TGO. Your 84, if OE, is equipped with iron Delco-Moraine calipers and smaller rotors than the 89+ which are equipped with alum PBR calipers and larger rotors. The following link should provide useful info/pics:

Many members on TGO upgrade. I suggest you advertise in our site's classifieds. My guess is you'll find a pair pretty quickly.
