Your truck brings back memories. I had a 55 1st panel. There were only 750 made so they are few and far between. If you weren't so far away AND if I wanted another project we'd probably be talking turkey. I follow eBay all the time looking for a one to replace my old 55. In it's current condition I would say you have a $1500 to $2500 vehicle there. Possibly higher. The RR wheel you refer to is probably the stock rim/spare tire. Do you have the hood? Take more pics (show all angles including the interior & dash) & list it on eBay. Put a $2500 reserve on it with a 99 cent starting bid and I think you'll sell it. Good luck.
