Anyone know if 90 and 91 tranny parts are interchangable? How about clutch parts? Both are 750 (749cc long stroke motors). I know the 91 switched to shim and bucket valves, so I know there are some difs.

Got a blown 91, and want to salvage as much as possible - cracked block, holed piston, don't trust the crank or rods, but anything else I can grab, I would like to.
