Liberty Rear Disk Brakes for A-Body

Im actually doing it on a b body so a little more than 3k but when searching to see if anyone else had done the Liberty swap yet I stumbled on this thread. I picked up the Liberty complete brakes, backing plates, rotors, pads and calipers at pick a part on Saturday for 60.99 so figured its worth a shot.

Now a b body I can understand a bit more.
