Spent the day under my truck with oven cleaner 2 wire brushes and a screwdriver, she's pretty clean now, but i still need to get under there with a stripping wheel and do a final cleaning before paint, that lye is nasty stuff, i had to stop about 4 times and clean up a bit.

Pressed my axle U-Joints apart then off to town again to pick up my new hubs, then to the auto parts store only to find yet again (3rd time) that i still don't have the correct spindle hub seals, so i went back to the 4X4 shop, they ordered a couple seals, but they also couldn't be 100% certain that they ordered the correct seal until they come in, the seal is in the same parts breakdown grouping for the SBK-1 bearing seal kit but these seals were not in the kit beginning to wonder if someone robbed the seals out of the kits i bought?? So if you have the small hubs and spindles on your truck (72 and later) i need some help finding the part number.

72 K20
Dana 44-5F MFG 1971
Smaller diameter hubs

(Hub bore)= Seal OD 3.000
(Axle diameter) = Seal ID 2.005

Shiny new parts! Looks good! From what I understand, the hub seals are identical between the Dana 44 and the Corporate 10 bolt like mine. I'm not sure if that's 100% correct though. It might be easier to find the Corporate version. Rockauto does list a National part number (472397) for a 72 Chevy Dana 44 with the following specs
Material Nitrile
Shaft Size 2"
Housing Bore 3"
Outer Diameter 3.005"
Width 0.312"
