Rear inner axle seals?

[D-50Sport]

Hi,

I need to find some rear inner axle seals for a 1980 D50 Sport 2wd. I ordered a set from Rock Auto and they were way off, looks like Rock Auto thinks the truck should have a Dana 60. I also tried a set off Ebay and they were not correct either. I pulled one out of my spare axle and there is no part number on the OEM seal that I can find.

Has anyone bought a set lately or have a part number?

Thanks

This site is great with exploded diagrams to find OEM part numbers:

Unfortunately, it only appears to cover Gen 2 variants of our trucks ('87-96 in the US), but most mechanical parts are the same as Gen 1. This page covers covers the rear axle ass'y (presuming that was carried over from Gen 1):

...where it appears item 33131 in the diagram is the inner shaft seal corresponding to OEM part nos. MB092288 and MB837719.

Some seal manufacturers offer search tools to find seals on their websites. Here's one for SKF: https://www.skfextranet.com/crsealsfinder/

Measure the axle diameter, axle tube bore and the seal width, then use the finder.
