Another route to find the vin --

When the truck got sold, most likely somebody grabbed the glovebox contents and stuffed them in a grocery bag, and pitched the whole thing into the attic. Equally possible, all tax relevant documents, invoices, and receipts are in that stack of shoeboxes in the spare bedroom closet. Somewhere in that stack is an insurance invoice or state inspection receipt. Some mechanics shops would include the vin number on their bills, as well.
