A red 1967 Camaro RS/SS convertible with rally wheels and a black interior was used as the pace car for the 1967 Midwestern Council of the Sports Car Club of America (SCCA) races held at Meadowdale International Raceway on Sunday, July 23, 1967. This 3.27 mile road course was located in Carpentersville, Illinois a northwestern suburb of Chicago. It was in operation between 1958 and 1968 before the track was closed. Remnants of the track still exist. The property has been turned into a forest preserve called Raceway Woods. The hiking and biking trails follow the original track layout.
I found the pictures several years ago at a web site that no longer exists.
This first picture shows the Camaro in front of what I believe to be the CP, DP, and EP class race as they go through turn 9.
2nd picture is a cropped version of the first.
