And how are your brakes with this setup? I just went through this on an E body. Those rear calipers were junk on the caddy's in the 80's. Probably the worst brake setup possible. Stick with the rear drums if you want cheap brakes.
I've had those calipers on the rear of my Dart for a while now and have no problem with them but I don't run them hard like I'm sure I lot of other people do. I think they got a bad rap in the eighties because people didn't use their emergency brakes and the calipers get out of adjustment then the adjusters eventually seized up and you're right they were junk. I keep an eye on mine and pull the emergency brake twice every time I take the car out.
My kit came with a new proportioning valve and the instructions called to take it apart and turn it into a distribution block. My brakes work good with no lock up. But again, I'm not auto crossing it or anything. Just normal street driving to cruise nights and such.
