About to start rear end swap... a few questions?

I think I did this correct... BUT!! with the lock nut washers on the nuts only fit on 3/4 way. If I take the lock nuts off then the bolts fit all the way on. The bottom bolt seems longer. That one fits fine.
What should I do?

Also, the seal on the Green bearing was a tight fit. I had to take a board and a hammer and tap it in there. It was pretty tight because of the seal. Is that normal?

Here are some pics... Does this look ok?

Thanks!
