1971 7 1/4 axle shaft seal

Can someone verify that the correct National Seal part number for a 1971 7 1/4" Axle shaft seal is a 8660S?

Well I just found the answer to my own question. No 8660s is the wrong seal. The correct one is National 484058 or SKF 13418.

IIRC the 8660S is for an 8.75. Whether its for inners or for a pinion seal, that escapes me.

I think 8660s is the seal that goes with the c-clip rear axle bearings like the 8 1/4 or 9 1/4.
