The real truth that I so far know is that they had 4 cars to do the first movie. As you may know, there is a scene in the first one,where the Cuda flips over and crashes. Don't worry too much. It was a 318 stunt car that had louvers put on it. From what I recall, it was a rust bucket that they destroyed in the movie. The best one that you saw Reggie in, was on a trailer with a camara on the truck carrying it. That one, was a really nice car. I'm not sure if it was original or not. I doubt it.(So many years gone by now) Anyway, there was a time crunch to get all 4 cars ready for the movie. The company that was in charge of getting the cars ready, was barely able to deliver them in time. I know quite a bit about all this because when I first restored my car the first time, I did it because the movie was out at the time. So, I decided to copy it from the ugly green it once was. Getting back to who, what, when, and where. There was a story, I believe in Mopar Muscle that talked about all the movie scene details. There is your lead on all the details about the movie and the car(s) I wish I could be more informational than this, but I hope this helps.
