All- Having leak issues with rear diff on 74' 40. Pretty sure the drain plug crush washer is shot. Plan is to go to NAPA with fill plug to size a washer/gasket. Do we know if the fix and drain plugs are the same diameter?

Looking at other posts it will be more in shipping than for the cost of an OEM crush washer. May have to go that route in the end if I can't find a suitable sub.

Think I have a slow leak around the cover also. After many hours of pain with installing a 4 wheel disc kit and the impact to the adjustment of the 3rd member, I had it rebuilt. Used the RTV that came with the kit and it's either crap or I didn't use enough.

Thanks,
LR
 
X2 on the crush washers, should be available at the dealer for cheap. Make sure you use a new cork gasket on the diff cover, I use that Pemex "right stuff import" around the bottom arc and studs ;) Some people swear just dry cork, but I've had that leak even after new studs/nuts -

Good luck!
