Original Headlights

OK, this may seem weird. I am restoring a 1968 cuda. Here is weird stuff, I would like to find out who produced the original headlights used at the factory. Does anyone out there know, or know where to go to find out? Could it be Tung-Sol? Trying to be "correct". Thanks for any help, Murray.

Hi! I know that Westinghouse and General Electric was supplier for Chrysler!
