69 Chevevelle question, help please

[macs69]

The original door panels are gone. It was converted, a couple owners ago from a parchment bench interior to black interior with buckets. I'm not sure if the back seat is the original parchment one that was recovered, or if it's a seat from a different car. Nonetheless, the build sheet isn't under it. When I pulled the back seat base up, there was red overspray on the floor from when it was painted. This leads me to believe that the car was completely gutted when the red paint job was done over the original burnished brown. The door panels are not the correct ones. They are black as well, and have SS emblems on them. The steering wheel is not the correct one, either, it's an aftermarket deal.
Wish I could be more helpful, but I think tracking the car back through a vin search would be the most productive. Getting information from previous owners could be very helpful.
If I provide my vin, or cowl tag info, does this help?
