Just acquired the Nov/Dec issue of Vintage Motorsport that has a report on the race weekend, and on page 121 a nice photo of the Brock Yates "Sunday Driver" car, owned by
Warren Agor. I did manage to speak to the crew of that car at the Glen, now owned by Jim Reed. Back in the day, I raced against Brock in that car at Michigan and the Glen.
I was surprised to run into the original mechanic Rick Dilcher, who built the car for Warren. Rick also was involved with Dimension Racing who built the 69 Camaro for
Peter Schwartzott and later the 510 that Peter raced. I knew them both from those days.
