i gotta change the rear diff cover gasket, its leaking. yay! anyway, i cant find the part number any place. does anyone know it? also i have heard there are different rear diff covers now available in the aftermarket. i have seen the tre with sightglass, but what are the other ones?

 

A lot of manufactures just use rtv on rear diffs oil pans ext.Thats the way I would do it rtv seems to last a lot longer than most paper gaskets.Just be sure to have both surfaces as clean as possable.

 

Im pretty sure its RTV. Thats what I used on mine a few years ago.
