Was looking at a van a few years back. Factory 440, auto, 9.25, solid body, tradesman, minimal interior mods. Seller had a story about it being a special order for an exec. Dunno about that but pkg included a set of engineering drawings for vans. Interesting stuff but doesn't prove the story. Anyway one other goodie included was a StreetVan kit and maybe a showroom display poster. Sold for stupid money.
