I found 3 different build sheets in my 1970 Charger R/T Special Edition, which I ordered new in late 1969. The first two were in ~1977 (one on top of the steering column under the dash and one under the rear seat bottom springs) and neither had the correct VIN. In 2016, when I was putting it back on the road, I (thank God!) found one with the CORRECT VIN on it in the springs of the rear seat back and it matched the fender tag, which is great for provenance documents to prove originality.
I’ve been told by three of the top Mopar muscle car history experts that this is very common. A VIN specific build sheet is attached to each major component for each VIN build rolling down the assembly line. Those components are sent to the appropriate assembly location at the appropriate time. Once the component arrives at its assembly point, it’s VIN specific building sheet’s job is done. A VIN specific master build sheet accompanying that specific VIN vehicle and just calls for specifically required components, for example, CXRA bucket seats; it doesn’t care which VIN is on the CXRA bucket seats. It’s just about having right number of CXRA bucket seats with the at the right time. The specific VIN didn’t matter, just the properties. Sucks sometimes, but that’s the way it was. Haunt all the appropriate forums for possible locations. Good hunting, gentlemen (and ladies)!
BTW, just for grins, the CXRA bucket seats installed in my car were all vinyl covered, not the leather ones specified for the Special Edition. That sucks, too…
