Thanks for all the info.
The truck has a title and was last registered in 2002. I talked to the CA DMV and they are requiring me to take the truck to the closest CHP office and have them do a vin inspection. From there they will see the newer engine not matching the old engine serial. They said the CHP officer will then use the body tag as the Vin#. They called this Blue Tagging? Anyways this seems to be the most logical method, except I dont have any way of getting the truck there since it isn't running. I believe the seller is going to have to step up to the plate. Also I do want to say I have 45 days since the day of closing of the bid to deal with ebay. They have been great, but I am trying to make this work with the seller first.
