I had the same problem.... the number is on the motor but Pa will not take that number. You will need to take pictures and a tracing of the VIN on the plate at the door or the other option is to take the truck.
Easy fix ( some will say dont do it) is to buy the truck and transfer the truck but dont put a license plate on it. Then after that paper work goes through ( use a Notary dont go to the DMV) then buy a set of number stamps and a new door VIN plate. Stamp it and take all that with you to the Notary
