Here is a unique photo taken at the convention, a view straight through three "8-door" Corvair 95 models, a Greenbrier, a Corvan, and waay back there, another Greenbrier. (Click the photo for an enlarged view.)
Corvair vans were "6-door" vans, two front doors, two right-hand cargo doors, and two rear cargo doors. That is, unless the buyer selected the optional left-side cargo doors to create what we know as the "8-door" models.
If you open every door on an 8-door van there is hardly any van left!
