Legend has it that they towed the Camaro into the dozer blades with a 383 automatic Challenger, one of 4 or 5 Challengers, (the rest were 440 4 speed cars), on loan from Chrysler.
That's a tasty morsel for Mopar fans.
Chrysler was not happy with the content of the movie and had them all crushed. A very unfortunate move on their part if you ask me.
See my home page for a very nice picture of a white '70 Challenger. It's not mine, but it's close, (mine has fat tires on the back). When I bought it, it came with Cleavon Little's, (Super Soul), original copy of the script.
Don't know how that script became part of the deal but it looks legit.
The DJ’s ( Cleavon Little ) radio station scenes were from the Goldfield Hotel, Goldfield Nevada. It’s supposedly one of the most haunted places in the USA.
