I have a 1981 xs650 special that I am working on chopping up and I just ordered a set of aluminum 1975 xs650 19" front and 18" rear for my build. Does all the guts and wheel hub & brakes from the rear change over from the mag to the spoke or will I have to find parts for that too? If so is there a place online I can just order the parts new? Hub, brakes, hardware, ect?
