I've always used 73 -76 A body disc brake set-ups. If you're switching the brakes on an A body, you need the upper A arm from the donor car, if it's a B body, you don't. New rotors and rebuilt calipers are cheap too. Make sure you get the proportioning valve off of the donor car or use a manual valve. I always buy a new master cylinder that fit the donor car ( made for disc brakes ). Easy switch and all Mopar. Gary On 4/9/07, Bill Provins <wiilbill66@xxxxxxx> wrote:
I have heard that you could change the old drums to early '70's disc brakes. Do you just pull off the spindles and calipers? Do they just bolt on to the A-arms or what all do you need? Wylde Bill
