Early 4x4 G van wanted

I'm interested in buying an early 4x4 van. My ideal van would be a 1967 4x4 Chevy 108 (long wheelbase) panel van with windows in all the doors (but nowhere else), with a straight six engine and a manual transmission. I realize early 4x4 vans don't come available often, so I'd look at any Gen 1 or 2 4x4. I'm not looking for anything too pretty. I do plan to use it off-road.
