850 Prop Shaft Seals

[1960 Starflite]

1975 SN 4294365 850 . I can't seem to find the prop seal dimensions. OEM 26-76868, Sierra 18-2002. Can someone provide? I like to have them in hand before tearing into this unit.
Wrapped someone's nylon rope around prop, I looked on this site without effect.

Thanks
