I have a 1969 2A Bugeye. Rover axles front and back. My question is on the Diff Nose housing that retains the pinion oil seal and keeps the outer pinion bearing retained. There is a thin metal shim/gasket under this housing. There seems to also be a gasket. None of the part suppliers show a listing for a gasket here? Any help would be appreciated if there should be a gasket and where I can source one. If no gasket is available my plan right now is to coat the thin metal shim/gasket with blue Hylomar sealant. Good enough? I did find the thin metal shim/gasket at RovahFarm. Trevor calls it a "Differential Nose Joint Washer". It is quite flimsy but I think I see no reason to reuse it. Any opinion on reusing? Thanks in advance for help. Cheers, Tom.
