Just came across more photos showing the white 1969 Camaro RS/SS convertible that was used to pace the Mission Bell 250 Trans Am race held at Riverside International Raceway in Riverside, California on October 5, 1969.
Glen Carter posted the first image on May 21, 2024 at the Riverside International Raceway (RiR) 22 Sept '57 - 02 July '89 Facebook page:

You can barely see the Camaro in the 3rd image. It is behind several people, ahead of the two Firebirds. The 3rd and 4th photos came from here:
