Nice try. The RS 60 (and its successor, the RS 61) didn't exist in the era of on-car advertising (save for the odd oil or tire decal), but there were a bunch of slightly different liveries (and assigned numbers) for drivers like Dan Gurney, Roger Penske, Bob Holbert, Augie Pabst, Bill Wuesthof, Don Sessler, Taffy von Trips, Jo Bonnier, Eddie Barth, Olivier Gendebien, Ludwig Heimrath, Hans Herrmann, Umberto Maglioli, Carel de Beaufort, Lake Underwood, Jack McAffee, Sammy Weiss, the von Dorys, et alia. They would be fairly easy to render, I suspect.
