Number 15 on the list was the GTO class and overall winner, Wayne Baker in his Porsche 934, co-driven by Kees Nierop and Jim Mullen.
After 12 grueling hours, they were able to outlast the faster GTP prototypes and GTX racers who had various mechanical issues during the race. Their winning margin of victory was only 90 seconds over the second place finisher, Bob Akin in his Porsche 935 with his co-drivers Dale Whittington and John O'Steen.
