Many midyears(if not all) actually had a by-pass hose there going to the intake manifold-don't remember what year it stopped, but that hole had an elbow fitting with a rubber hose going to the intake. They used the short leg water pump too like our C3s.

Hmmmm.......so that hole could be used as the temperature sender source? Or heater hose source?
