I am so lucky that my Burb came with all the seats in it. As a matter of fact the only thing I have found that is missing on the entire truck are the cables and reels for the clamshell doors. The previous owner swapped them in place of the original barn doors. Evidently he couldn't find a source of those parts. As an added bonus he included the near pristine set of barn doors when he sold me the truck! I sold them to another Bolter for what now appears to be a very reasonable price. I guess I could have gouged someone on Ebay if I wanted to. Just trying to help a brother out.
