Here are a few pictures of what looks to be a 1968 Camaro coupe being used as the pace car for the Stardust Grand Prix SCCA Can Am event held at Stardust International Raceway outside Las Vegas, Nevada on November 12, 1967. This was the last round in the Championship.
Notice the Camaro on the right side of the first picture with its left turn signal illuminated. To me this shows that it had just turned left off the racetrack and into pit lane leaving the Can Am cars to receive the green flag starting the race.
The third picture shows the same Camaro in the paddock area. It is on the top left of the photo with its trunk open. It appears to be a light colored car that has the standard tail lights indicating that it was not a Rally Sport, just like the Camaro in the pit lane. See a larger version of the picture here:
