Well knowing MOPAR anything is possible. My father worked at the assembly plant in Belvidere for over 30 years. The stories I could tell. Anyway, my brother bought a brand new car that was assembled there and bought from a local dealer that according to the numbers can never exist. It had an engine that was not an option, options that didn't exist
and a build sheet that was one of a kind. All the paperwork was in order from the factory though.

I have seen cars that vin numbers were royally screwed up when they were pulled from the line to have something repaired before plugged back in.

Mopar had some real challenges in the 60's 70' and 80's. That is what makes many of them so unique.
