THE BLACK BEAUTY #1 VIN
NOTE: Carefully look at the rivets that attach these plates to the vehicle. Notice their shape. They are not consistent with rivets used by the Chrysler Corporation. Therefore, we must conclude that these plates were removed from the vehicle at some point during its life. Removal of or tampering with such plates is a federal crime.
