64 Dodge Dart vin # attachment

The research I have done indicates that the serial number plates were installed with a panel bonding type of adhesive. The holes were punched into the plate and door frame to align it while the adhesive cured. I have removed a couple of plates by sliding an old paring knife between the plate and door frame and tapping it through with a hammer and never encountered any resistance like a spot weld or ripped the plate as if it were spot welded. They also had a black material on the back like some sort of glue. I put those back on to the cars with a dab of urethane from a windshield shop.
