Doesn't the bearing race just sit against the larger diameter backing in the housing? I don't think it contacts the seal at all. It's been a few years since I rebuilt my rear axles so I might be remembering it wrong.

For what it's worth I think my seals were driven in to about the same depth as yours

The machined area on the axle shaft is about 1 inch wide, so as long as the back of the bearing or a shoulder on the axle shaft is not pressing on the seal, I should be OK.
Thank for the pic Kevin, that looks like how far I got the passenger side in, and the one I was concerned with. The driver side went in about 3/8 inch deeper, and I was happy with that one...Guess I am over thinking/worrying here.

Measure twice cut once, or in this case....measure once and hit twice. I measured the installed depth of the seal, and the position of the sealing surface on the axle, and then decided to give drive the seal 1/2 inch deeper. Now it should all line up.
I installed the shims and paper gaskets, and made a tool like in the shop manual to measure the endplay....I'll get to that soon and remove shim(s) as needed. I'm gettin' back into the groove.
