4 speed crankshaft

if the cranks depth is good you can use a the National bearing FC69907. This bearing fits in the register for the converter. It uses the roller type bearing instead of the bushing that would normally be used as a pilot.
If the depth is not deep enough you will need to remove grind off 1/2 to 3/4 of an inch from the input shaft of the trans. I do not know what the minimal spec is for use with auto-crankshaft with 4-spd trans though.
