Did the earlier 50's pickups as in 51 come off the assembly line with a vin tag on the pillar which was a serial # not related to the engine # and depending on what state (as in Texas) it was titled under the engine # not the serial #. If that is correct you could find a truck titled under the engine # and never changed if you could do a national data base search or search all the states using the vin tag on the pillar there would be no such truck.
Please let me know where I am off on this thought.
Thanks

In my younger years I worried about the return on my principal now the older I get I worry about my principal being returned.
