No, it isn't because it is an impossibility. The VIN only appears in one place on a 1966 Mopar, the VIN plate in the door jamb. The number on the fender tag and radiator support is the Shipping Order Number. The two numbers can only be matched with a broadcast sheet or IBM card. The block will be stamped on the front under the left head, but that will not contain the car VIN, either.
