Regarding Les Stanford Chevrolet. I picked this 1969 Nova up a few years ago from this site. It was sold from Les Stanford Chevrolet and I just sent out for the NCRS documents to confirm it. It has been a race car since the 70s and still looks the exact same today. I put in a link below to what it looked like back in the day. I'm not sure what drag strip it was.
