If it's a 99-c.i. engine, any 99-cube (non-racing) crankshaft will work. Just change the reed stops or swap reed blocks to the donor crank.

If it's a 90 c.i. there are a few different styles, '64-older and '65-'70. The big distinction there is whether the upper and lower crankshaft ball bearings are pressed into the bearing caps and a slip-fit on the crank (older), or pressed onto the crank and a slip-fit into the bearing blocks (later-models).
