I have a broken part and need a replacement. I have a '65 chevy II with a '66 194ci chevelle engine. Now the top radiator hose conects to this pice that is bolted to the head. Now this piece has two parts that bolts together. The bottom piece has threads for the temperature sending unit. Now were the threads are for the temperature sending unit theres is a small crack. The piece is aparently made out of aluminium, but I was wondering if I could weld it to fix the small "split" type of crack. I don't think it was caused by the sending unit Anywho, I was wondering if I could weld it or were I could find a new one, NAPA han't been much help. thanks
P.S I know it sounds kind of like a riddle.
