there are body production line numbers stamped on mopars----on some the front 6 digit number is on the radiator support in plain view and the matching rear number is hidden under the rubber gasket of the back window--near the package tray---these numbers match the data plate and the broadcast sheet----in some years the front number is moved to the area of cowl near windshield wiper motor----these numbers have nothing to do with the vin number....
