Of course, I could also do the story version. In the story, in 1967 Jack hasn't yet started to come into any of his father-in-law's money. When he shows up at Ennis's apartment, he's wearing the same old Resistol and driving the same old pickup as in 1964.
So maybe I could look for some 1940s style pickup--in green, I think the story says the color is.
Guess I'll have to start looking for a laundromat building with a second floor to it.
