Hi all. New guy here with a noob question. I’m looking at a 1955 bel air convertible. Now, I was under the impression that all vin tags were welded on horizontally. The car I’m looking at has the vin vertical. The owner says he’s owned the car for over 20 years and swears it’s factory. He also said the vin tags came either horizontally or vertically depending on the plant the car came from. I notice that all cars that have the vin tag horizontal also have two little vertical holes that looks like it would match a vin tag. Any help is highly appreciated thanks.
