I asked around about that car, and was told to check for clues at motion dragway in IL, it should have ran there in the mid 80s from what I heard. There is actually quite a bit of footage at this dragstrip from back in the day, maybe he can find some folks that remember the car.
Its nice to know what these cars looked like back in the day, but I doubt he would put it back that way, considering how nice it looks now.
Some footage starts later in the attached clip, you can see some big body mopars...(like check out around the 4:40 mark, as example, not sure if that is a hardtop, then near the end, there is a tail shot of I think a road runner for a split second).
