727 tail shaft seal

Anyone know the ID size seal I need for my 1970 plus 727 trans! ( Tailshaft seal)

Was hoping to just grab one at the parts store but they have to different sizes

Thanks

They have two different part numbers but AFAIK there is only one size.
As to the two PNs;one is a common dust seal, the other is for a seal with a boot. The boot keeps the slip yoke from rusting. The rust would chew up the seal and a bit of the bushing. Get the booted one.
