I remember the Johncock win. The mechanics made adjustments to his set up on the final pit stop. I watched as the pit crew adjusted the down-force up front. After the race I remember Johncock saying, paraphrased, “Yeah, they made adjustments and the car went to hell!” ;-)
Also, Mears made his move too late in the race.
Gordy was a real punk. Great driver but a real nasty sumbitch
