Questions: Do you also carry the drain plug on the bottom of the differential? Mine has the square internal hole and it is messed up beyond repair but this plug would reduce the ground clearance and I'd risk ripping it off and breaking the differential housing. I checked all auto parts stores and was told that there is no such part. Plumbing supply houses only have the same style plug as the filler plug. I really need 2 plugs for a Dana41 and a Dana25. Thanks for your help, as always.
