Mark, I have done as krv3000 (Bob) has suggested. It was an aluminum casting that had a cracked off part of a threaded mounting ear.
I threaded a piece of copper to match the half threaded hole and took it to my aluminum welding wizard. He built up the rest of the "ear/tab" and when done and cooled down I unscrewed the copper piece and cleaned up the welding and the part was new again.
Just make sure the copper is smooth and not tapered to aid removal .
P.S. please add London Ont. to your profile so old geezers like me won't wonder where the hell you are in this tiny country of Canada you are.
