Similarly my experience with diffs is limited and to the 1933 on type, but no experienced replies yet. The pinion bearing in its fully home position should be a good fit in the diff housing . (With a ball pinion this makes repeat removal to check mesh awkward. Have to peep thru the plug hole although some claim adj success with diff half assembled.)
The housing for the a/c bearings is in my expereince not normally a tight fit in the diff casing and need not be as lateral loads are modest . One of the a/c races has radial clearance for its outer ring; often find shims etc in an attempt to "fix" this!
As with the side bearings, care is necessary to get a.c bearings the intended way around and not apply pressure which may load, indent and ruin them.
If for some reason have to push hard on a ball race, beneficial if it rotated whilst do so.
