I was told the input shaft retainer was the critical item for centering the transmission. Since the nv4500 and the sm465 had the same size retainer, and would fit snugly in each other's bells, the bolts only needed to hold it together.

I know what you mean though, about those bolts being inaccessible. So far, I've had the best luck mounting the bell, and then installing the tranny. The time I tried to install a bell and tranny together, didn't go so well.
