1966 Series 75 Differential Pinion Seal Size?

[rajeevx7]

Is the seal a 3.25” of the regular wheelbase or 3.75” of the commercial chassis?

Call me crazy but I like to have all my parts ready before I start a removal and install

Thx!

It’s a 3.25”! I put the how to in my build thread and the pics are in my album over there.

Thanks for supplying us with the answer.   Now just have to remember it.
