1965 Dodge Dart Charger

Your antenna scenario sounds like something I've been involved with. Back in 1973 a friend took his 1965 Barracuda to a ball game in Denver. When he got out of the game his antenna had been snapped off. He ordered the replacement from the Plymouth garage with the part number that was supposed to be correct but when he got it the new part was some sort of "fit all" Motorola antenna. The parts department checked the numbers and all was correct by part number so they reordered and got another "fit all" piece. We had to go to a wrecking yard to get a correct replacement.
