Oil seal part number?

Does anyone know the factory part number for the oil seal inside the speeodmeter pinion housing on the A-type overdrive gearbox? The parts book is stating "NSP" which I think means non-stocked part. The Moss number is 120-710.

Thanks,

Paul B.
 
Paul,
They don't really use factory PNs for these; you just need the dimensions.

I just pulled the pinion assembly from my spare 28% OD trans.
Bore size is .75" and Shaft size is .375". Thickness is .25"

If you wind up getting the Chicago Rawhide seals which are much thinner, suggest installing two of them stacked.

Oh, yeah, I've got the seal. I jsut thought it was odd that there was no part number for it in the parts books even though it would be something that would get replaced at some point.
