I am assembling my diff at the moment and have spent a while trying to find what thickness the gasket is between the two halves of the housing.
It is very important that the gasket is the correct thickness as it is the medium by which the diff side bearings are pre-loaded.
I hunted through about 8 parts books and manuals and found no sizes (Henry wanted to sell us gaskets)
I looked in the big Australian Workshop manual (M.G. 2 pdr. and 3" Mortar) In there it says they are 0.010"thick, which for you young un-edumakated and otherwise metricated guys, it is 0.25mm (= 0.0098") near enough!

The part number for the gasket is BB-4035 and state side, Best gasket sell them. I made mine.
