You can adapt front brakes from a bunch of later model Mopars (B, F, J, M-bodies), not too hard to do. Somewhere around here I have a copy of an old Mopar Muscle article (or maybe even High Performance Mopar!) that details which cars can act as donors and what to grab off them. If I can find it and you have access to a fax machine, I'll fax it to you. Send me a PM with a fax number.
