Couldn't tell you what swaps into what. A cycle salvage would probably have a compatibility listing for that one. A big thing with these was the frame designs changing which could change the mounting in the chassis, along with obviously changes to the engine itself. If you can get the whole donor bike you might be able to do the swap, but if the wiring and ignition system is different enough you'd be wishing you had just fixed the gearbox in the one you have.
