Walk in slap your paper work down and pull out your credit card , I seriously doubt anyone at dmv knows the specifics of your 69 chevy truck , With no vin reference on the engine how would they ? let alone looking for hidden vin #'s on the frame or even have a clue about the spid ... if it even has one in the glove box , they're 50 years old ,Probably older than the dmv agent who drives a kia and doesn't want to walk out in the heat ...
