Can I put a "J" crank in a 84 GPZ case? can I Put a 84 tranny in a 81 case and so on.
Yes, in both cases.
Everything will fit in your examples.
A GPZ is a J motor, just better cams,pistons etc.
I believe, (but am not sure)that early J motors have a smaller piston pin diameter than later models.

Yes, definitely........Are the main cases the same between the sahft and the chain drive engines?
I think the only difference is the transmission output shaft.

There is a monkey wrench to your plan.I was wondering if a shafty could be converted to a chain drive system by changing the shaft drive cover system and the swing arm and wheel.
The transmission output shaft is different between the shaft and chain bikes.
You will need to split the cases and install the output shaft that allows mounting of the chain sprocket.
It is possible you could machine something to work without splitting the cases. Sounds like the kind of challenge I like..
