You know, I thought about that... Subing a TO20 front bearing. Never tried but looks like a maybe. Don't think a 134/145 center thrust would work, no thrust surface on the center journal of the crank.
Also wondering if removing the shim so the crank gear will go further back will allow the pulley to still tighten down. Might need to shim the front of the gear... Where does it all stop! By now I would be talking myself into pulling it out and fixing it right.
And... what are the consequences of running it with the crank shifted that far forward? What else is miss aligning? Rods binding? Starter drive hitting the front of the flywheel?
I hate guessing and short cuts!
