. "The 1991 Peak AntiFreeze 500 was a Winston Cup (now Nextel Cup) event held at Dover International Speedway on September 15, 1991. Harry Gant led 326 of the 500 laps in route to a dominating one-lap victory on Geoffrey Bodine. It was the only one-lap victory of the season. Points leader Dale Earnhardt led 21 laps, but a poor 15th place finish shrunk his points lead on Ricky Rudd (7th). Stats"@en . . "1991 Peak AntiFreeze 500"@en .
