I am new to the group.  My brother passed away in January and left me his car collection.  He was an avid Firebird / Trans Am guy.  I know very little about the cars.  The car I am working now did not have any rear brake calipers on it.  Since I assumed that factory rear disk brakes on there cars was rare, I ordered replacement calipers that fit rear disk conversion cars only. I am told these will not work for factory disk brake cars.  After getting the rotors off, I cannot see how this wouldn't be a factory disk brake setup.  Since you guys are the experts, I am hoping you can confirm one way or the other with these pics.


Thanks in advance!

The rear disc conversions often sold are for rear ends that originally had drums. They are different. I assume it's what you may now have.
