My '71 ain't a '71...or is it?

Package tray partial VINs are on 1970 up 29 models, the Duster, Demon & Dart Sport models.

The hard top '23' models have been found with the partial VIN on the drivers side rear truck gutter as well as the passenger side rear trunk gutter.

So if you do not find one on the drivers side, check the other side.
