Factory build sheet discrepancy

There are factory mistakes, but generally with letters/numbers that do not belong there or a number omitted. After 50+ years it is likely that the drivetrain was changed.

Working on documentation as this was my wife’s grandfathers car and he passed shortly after I bought the car from him. The story he told me is he was the second owner since new, and simply had it as a weekend car.

I need to get the car on a lift to confirm the drivetrain, but everything else is numbers matching on the car. All options that the car came with are present. Has the certicard in the glovebox to boot. Haven’t been able to research the Chrysler service codes on the sheet yet.
