There is another process for them to assign a new VIN, called a blue tag. This is no different from when a VIN tag falls off and is loss, CHP attaches a new blue tag after verifying it is not a stolen vehicle. If the vehicle was never manufactured with a "second" stamping then they can't require it, newer vehicles do have additional VIN stamps on frame. Are you certain there is not a partial VIN stamped somewhere on the frame? Ask DMV about the original engine is missing so there is no VIN and you need to have a new one assigned.
