Ouch!! It is kind of an ugly duckling lol, but found it so period correct. So I spent almost a year restoring that camper shell. All new wood, insulation, wiring etc. The back door should be removed first before the rest of the camper taken off so you can set it down level. You'll have to remove that exterior light first toraise the door high enough to remove it.
As far as the truck goes, it is a factory white SS with an automatic and had 411's in that 9". Told it was owned by a woman in Northern California. Makes sesne now with the options it came with.
Like Tim says, come out to Vanfest father's day weekend, then Milford Mi the following weekend.
I'll send you an email rather than boring others with my rambling, and yes, I have another SS and a 67 short 8door panel van.
