In 1980, Gurney came out of a 10-year retirement to help old friend Les Richter, the president of Riverside. (Gurney's adoption of the number that became most closely identified with his career, 48, was a nod to Richter's NFL number.) Gurney agreed to drive a second Rod Osterlund Chevrolet for one NASCAR race as teammate to 1979 rookie of the year Dale Earnhardt. For added publicity and supposedly as a condition of allowing Gurney to drive in the race after a 10-year layoff, Richter insisted that Gurney attend the racing school run by former teammate and friend Bob Bondurant (Gurney and Bondurant had shared the GT-class-winning Cobra Daytona coupe at Le Mans in 1964). After Gurney's refresher session, Richter called Bondurant and asked how Gurney had done. "He didn't need a refresher," Bondurant reportedly told Richter. "He was faster than me then, and he still is." Ticket sales surged upon the announcement of Gurney's return. In a Chevy MonteCarlo painted white with blue and carrying his famed number 48, Gurney qualified seventh and easily ran with the leaders. Displaying his usual fluid style, Gurney raced up to second place, and was running third when the input shaft in the transmission let go, something Dan later said he had never seen happen before or since.
