That rear disc kit from all pro looks like what I want. Price is right too. I gave them a call to ask if the callipers have E brak provisions, they dont. All the guy that I got on the phone could tell me was They use front callipers off 82 GM Monte carlo. Wierd. You would think they would use a more modern rear disc calliper. Anyway, any one have this kit that can tell me the dia of the rotor, center to center of the calliper mount holes, and roter offset? My goal is to sorce another calliper with E brakes. I cant see paying $500 for a rear disc conversion only to have no e brake and have to pay an extra $300 for a X case E brake.
