In another incident, Yunick showed up for a race with stock rear fenders that partially covered the rear tires of his Chevelle. The car qualified well due to improved aerodynamics but the other teams were laughing and wondering how he was going to change the tires during pit stops. After qualifying, Yunick promptly cut out the rear fender openings. The other teams complained to NASCAR but Smokey said, "The rules say that I CAN cut out the rear fenders but it doesn't say WHEN I can cut them."
