should fit since both are 3/4" axle. I put a 3/4" deuce wheel on the back of my 94 fxstc just had to find the right spacers. The brake rotor/caliber worked fine, I didn't reuse the stock pulley since I had to get a thin one to clear the wider tire/wheel.
the bearings may be different types with the later using sealed an the older using the open kind you have to back. torque values may be different, not sure if the bearing pocket is the same size to interchange them.
