engine to bellhousing runout spec 904?

Put a new bushing in the pump, use the proper tool to align the front pump halves when assembling the pump, if the halves aren't properly aligned the bushing will fail & the seal will leak...
Yessir, I did all the bushings except the tiny one inside the stator support. That one looks like new. Not sure what tool you speak of, I just flipped the pump upside down and reinstalled in the case to align it while torquing the bolts.

I saw somebody used a huge hose clamp to align the halves. Wonder if you could set the converter on the bench and lower the loosely bolted pump/gutted case onto it and torque the bolts from inside.

I might never finish this trans lol
