you're the distributor guy. I thought you knew this stuff? lol
I was wondering about the vent caps... Tough to say with all the variations. Even 'survivor' cars are very unlikely to have their original cap. Unless you know the original owner and he's got the original cap sitting on the shelf, Put the used one in the new box and write the date and what car it was from...My dad would hang on to used parts like that.
