More useless information. Using a regular 3/8 UNF bolt with a long enough sh=
ank could potentially allow the bell housing to hang 0.001 inch low on the e=
ngine back plate.=20
The play in a new input shaft bearing will allow the tip of shaft (where it e=
nters the bushing in the crank) to move, much more than 0.001. So is alignme=
nt really an issue with tolerances this small?=20

Perry I  would think that the bigger problem would be the gear alignment.
If the forward end on the input shaft were to be displaced the input gear
would engage with the laygear at an angle. .. not good.
