Well I really screwed the pooch back in Cincinnati. The snapped oil pump stud was in there good. We took the motor out. Tried an easy out, tried a larger easy out, tried a drill and a punch to break threads, and then we tried tapping threads for a little larger metric bolt, and now there is an insert for a 1/4-20 bolt. It looks fine, I guess I can't sweat the details too much. The boys let me do the work, they didn't wanna mess it up more.
