If i had that problem i would go to ABSAF. They do a metric crank / bearings and line bore the cases. Or get the right company to re-weld and line bore and choose a different crank.

I like the NEB crank / Omega forged piston set - up, but that is me.

On the last engine i rebuilt i used all C3 bearings:

Drive side roller = NSK

Drive ball = SKF (This is surprisingly cheap due to the popularity of this metric bearing).

T/s = Original Hoffman 12 roller sigle lip. I will not use anything else here (R and M also ok.) VERY RARE AND HARD TO FIND.
