So who is stamping out these correct VIN tag reproductions?It's been discussed many times. There is a legal way to get a VIN tag for our cars. It requires a build sheet, fender tag and correct body stampings to confirm the legitimacy of the car.
Edit: 14 minutes and he contacted me.
Cowl tags are similar to fender tags, Gm doesn't have a Vin on them I believe but references trim etc...I know a guy that got one made. He told me it was not easy. They wanted to be absolutely sure the car was real. Perhaps cowl tag refers to VIN?
