65 barracuda Commando 273 /Formula S?
I had CHS do the history on my 1966 and they did find the IBM card and sent me a bunch of really nice information, factory pictures, advertisements and more. Really nice people.
Another nice thing about the early years is if you want to go stock there are plenty of date coded motors to put a valid drive train back in your car.....no serial numbers to fret about....
