On a '69 Camaro the last six digits of the VIN and the 'ident number' number were on the body and chassis broadcast copies. The ident number is the number on the body tag. The full VIN and body tag number were on the window sticker & shippers' copy.
The VIN was not stamped on the body tag on cars shipped to the states. Some export Camaros did have the VIN on the tag; others had an additional tag that had the VIN stamped on it.
