IF it were 69 or newer the vin or partial vin would be in the hidden locations. This is a 68 there are no hidden vin's. The numbers on the core support and trunk lip correspond to the fender tag and not the title or vin. If no vin tag, fender tag and or build sheet... there is nothing.
To take this to DMV or police to check or reissue a vin there is a chance they will seize your vehicle.
