Borg 35 prop shaft seal

[Lemp1953]

Hi all, does anyone know the dimensions of the seal that goes into the gearbox at the rear. I've been handed one and it looks a bit small on the outer ring. I've 20240704_183546.jpg enclosed a photo

I.d. Is 1/3/8”
O.d. is 2”
depth is 5/16”

Seal part number is AS 195 137 31 nbr material

believe the oem is gaco 43070

ps a tape measure isn’t a great deal of help for measuring a lip seal though.

no offence.

cannot tell from the photo, possibly the seal isn’t for auto?

check fit to housing / shaft maybe?

or measure with a vernier?
