Talking to a friend last night and he told me that T-3 means something - like and engineering term, test or something like that. He said that Mike Joy was talking about that subject during a Barrett Jackson auction broadcast, but can't remember the details... I know that the T3 headlamps were made by Guide, which was bought by GM in the early days to be a subsidiary of Delco-Remy.
Anyone have a clue?
