My mom just gave me the title for 'Old Red' (the '51 3100 1/2 ton that has been in our family for 50 years). The ID number on the title is not the VIN found on a plate on the driver's door jamb, but is instead the serial number stamped on the block (JBA552048).
What is you all's experience? Does your title have the VIN, or the stamped engine number? I'm thinking about telling my tag agent that I want to change the number on the title to the VIN.
