Guess this part game

Time to revive this thread as I have stumped some Bronco gurus already. What is this?? Found inside the engine bay of a 1 owner 71 6 cylinder

Early hood lock. Had a little chain attached to the hood that slides into that lock.

In the motorcycle world it would be an old-style helmet lock that had a chrome piece inserted into it holding the helmet in place.
