Herb is correct, they are difficult to identify who had the car unless you know the full history of owners. Two of mine I do, (luckily only the 4th owner on them) but the third is a mystery, although the body is perfect and basically original paint with one lame lacquer respray.

I doubt the car posted is the Sox Car, they only had one real R023, the others were GTX's or clones. The original is accounted for from what I understand.

I have a spreadsheet with a majority of the VINS and SO numbers for the R023 cars and some of the W023 cars.

Just my 2¢
