You have a good eye. It was built by Don Hardy for Roger Denney in 1975, then he sold it to the Rod Shop. This is the "famous" black Rod Shop Colt that Bob Riffle ran 8.21 at a match race in Orange County in 1976.

In 1977, it went to Carlton to use as a PS match race car, as his altered wheelbase Colt wasn't popular with the track promoters as a PS match racer. Donnie went 8.08 at 169 in this car a week before his death. Someone already posted a picture of this car in white Carlton colors with Ronnie Sox's name on the window. The photo was taken at Indy in 1977.

I bought it from the Rod Shop in late 1978 and raced PS and FX in 1979 and 1980.
