Ed,
Here is the info on the Vin for your dads car, anything else I can do to help let me know. Maybe someone here from PA can interject on DMV hopes(Marlin?). The clickable link below can help anyone here for decoding Chevy VIN's and Cowl Tags up to 69, go to the site and click on "Decode VIN or Cowl Tag".
Thanks,
