got to thinking about this and how to do this for reasonable money wise. Here is what i came up with after some research. What if you put stock 50 rotors from front on rear same bolt pattern same center bore. only issue could be backing plate spacing but your going to, have to modify it anyway for caliper. Then use a caliper from 88-95 Isuzu Trooper has rear discs and caliper has built in manual e-brake that is designed to work with hand lever. So mods needed would be backing plate, custom caliper mounting bracket, brake line, and maybe ebrake attachment to cables. did i miss anything.
