I wish I would have gotten more info on them when I saw them. Went back a couple weeks after I saw them initially and they were all gone! I still have the guys card, so I might call him to see what became of them......
They were a mish mash of trucks. The main truck had 1969 Texas license plates, but I never got to check the VIN or look at it that closely. I wnat to say it had a D44
The wrecked one I saw on the lot had a Dana 30, so it was probably pre 72. I asked if they rolled it in the movie (I never saw it) and he said they only hit a cow?
The tub they used for close ups while the actors were in the truck was a 77 tub with the gas doors. Not sure what happened to the frame and running gear off it--maybe that is what Mad saw.....
