I know there are donor cars people talk about that you can convert over to fit on your car for the disc brake conversion but not for sure on which cars they are. I am looking at a 91 Camaro or the other is an 82 or 83 Camaro to take off there brake system and put on my 69 Camaro. But, not sure if these cars fit in the donor catagory. Any help would be greatly appreciated before I invest in the systems. THANKS
