Ahh perfect! @starkey480 thats who it was. I think I even commented on it that I need to do this… do you have a link for pic / process?
Essentially just cut 1/8” deep notches on the bottom of the diff to give the welds something to bite to. Lay beads down. Put new diff cover on and grind the welds flush ti it. I bolted a thick piece of aluminum to the face of the housing so that I could weld right up to the edge
