It cant be repaired I need new mount. My mechanic told me that its been welded very poorly before(which is obvious if you look at it below where the pic was taken) and that the heat from the first attempted fix weakened the metal and caused the crack.

So I was hoping that im not the first one this happened to and that someone made aftermarket mounts that could just be welded on.

My mechanic is a fabricator as well and quoted me $500 cash to remove the diff, cut off old mount, fabricate new mount and weld on and reinstall the diff.

EDIT: I have a buddy with a welder that would cut off and weld new mount on for free, so was hoping to go that route.
