The vehicle(s) of my youth... I think I had four or five of them in succession. None of mine had windows but it was the height of the custom van craze, portholes and sunroofs were in! I bought them when they were 10 plus years old and tired, then ran them into the ground all the while aspiring to customise them. As a vehicle they were basic, noisy, cold and rattly. They came with 6 cylinder engines but the small block V8s bolted right into place. Much better. Standard transmission- 3 on the tree, no power brakes, no power steering, no power anything.
They were much like a Volkswagen van but more useful, more stable with more power and a flat floor, you could carry motorcycles.
