Having trouble finding one. The part number on the seal is 1404504 which cross references to a national 7216. I ordered the national seal but it’s too small.
Next I ordered what I thought was the correct item from Old Mopar parts using the mopar part number out of the parts manual but again the seal is too small.
The ID is 2 1/8 inches and the OD is 3 1/4 inches.

There was an older thread on this which listed some part numbers but I had no luck with them.

I think the national 6845 might work but I cannot locate one.


Any info is appreciated.

Check with Birnbaum's, I think I saw this listed. The Firedome had the larger pinion shaft.

Searching on the shaft and bore sizes at the SKF website turns up a 21336

Thanks all.

From the previous thread this is what I need

https://hagensautoparts.com/cdn/611/796/61179622920fd3e0e646d710c7bb...

Unfortunately since I have a wagon they are hard to come by.

All the referenced part numbers above turn up as a dead end.
