Dana Axle seals

[edison1970]

Does anyone know if the axle seals are the same in the 8 3/4 and the Dana 60?

I believe the inner dimension is different

this is the listing I found
DANA 39246 {#DS39246, EOTZ1177A} Spicer; ID = 1.710", OD = 3.040", you should be able to cross reference from that #
A different manufacturer lists the same seal for both 8 3/4 & 9 3/4" diffs .
My recollection is they both used the same bearing , adjuster system & seal , but it has been a long time since I worked on a factory Dana , we used to build a lot of Danas from truck floating units !
