Help decoding vin, tag and rad saddle

Whats it supposed to be?? From the top vin its a 68 cuda?? But the bottom vin on the fender tag should be the same. Something on the tag dont look right

On 68 the vin last 6 are not on the fender tag. But the numbers on the core support should match the 6 on the vin tag.Which they do.
