I worked at Toyota for 20 yrs, the newer diffs are rolled steel , I would put a protective ring around drain plug. If you are not good at welding, how are you at brazing , it is kind of like soldering.Thanks guys.
I will keep the add-on magnet in mind.
Thanks eggman for the tap offer. I'll just buy one if I go that route. I have never drilled or tapped cast...
The D&T would certainly get it low. The drains on my Toyota diffs are all protected by a welded-on or cast-in ring around the drain. If I weld a bung on the cover, I might do something like that.
I am not much of a welder, and don't picture me welding a ring around a bottom plug.
