I tried to find out the same info on my car. I was told that only the Demon builds could be tracked in order. You can however, email dodge with your VIN and ask for the production info on your car. They will tell you things like the date it was built, and its "one of number" which you already know.
Below is what I got back from Dodge. The build trees that PLUMCRAZY used to do were much more informative as according to his much more detailed report my car is actually a 1 of 2 identical cars built. Where as Dodge says one of 22, because they don't account for options like a block heater or summer tires and so on. One better is the factory tracking data I got from R/S back in the day. I could tell you exactly when my car was in framing, when it was in paint and so on. Don't think many guys got that report from him back then.
