I just took out my rear end for the swap I’m doing and I have a perfect rear disc brake setup off of it. These calipers are hard to find, and mine are in great condition painted red. I’m selling the entire setup for $250.00. This is a very hard to find setup and would be a great upgrade to any rear drum brake car. My friend did this upgrade to his 87 Cutlass, so i know it will work on there. And the brakes will obvisiously work on the Camaro’s and Firebirds of the 1980s. Possibly work on monte Carlo’s also? You’ll have to do some research on some of the applications. I’ll also give you the rear end with them if you want it. It is also in good condition. PM me if you have any questions.
