Moser housing & axle package axle seal help...

As a wild guess, I’d look at the 8.75 replacement seals. Most axle and housings are a copy of the originals. But as I said that’s a guess as it uses factory style housing ends.
The outside diameter is the same as a factory seal but it's the inside diameter that I'm concerned with. Going to measure the axle this evening & see what my measurement is. Thanks.
