Well, I don't know exactly where the poster of that ad got his info, but it is a very late build (7-7-65). Things were a little different in the 60's with Mopar, with far less ducumentation available, but maybe through factory doc's you could find out this info. I know the high dollar late 60's and 70's cars are much more documented and it's relatively easy to discern how many of what each had, especailly when there are only a few examples built.
Given enough time, you can probably document just about everything these days, but without proof, it's just a story!! Geof
