well Jim sorry to hear your troubles, but I have no idea why you would need a '93 rear set-up for the motor to fit. B.S.
to give you an idea, the '97 rear wheel uses 3 bearings/ the '93 uses 2.
Cant seem to remember when they changed the swing-arm /caliper mount design. Some mount on the inside, others from the top.
If nobody else chimes in, check with Sandblaster. He's a commercial member, OEM Cycle, with good knowledge and a good parts supply. He may have the parts you need.
