Was working on a 1963 Ford Falcon in the early 1970's. Had a leaky radiator.
Upon pulling the radiator I found a Craftman's 1/2" socket wrench where the bottom of the radiator sat. It had over some period of time rubbed a hole in the radiator. The wrench didn't fair to well either.
Took it to Sears an got a brand new one. I still have it and use it today.
