The backing plate must be cut down and reinstalled to retain the axles. Axles centers will have to be machine down to fit the rotors--the bolt apattern is ok. Then a bracket will have to be welded to the rear housing to hold the caliper. It is possible the rear disc from a late Camaro of Firebird could be adapted also. The other way I described I have done before but it does not provide an parking brake set-up so the latter would seem to be better---paul
