In 1969, after signing with Smokey Yunick for the Indianapolis 500, Leonard drove the #13 Smokey Yunick Ford Torino Talladega at the Medal of Honor Firecracker 400 at Daytona International Speedway. Leonard would crash out after 47 laps and finish in 31st place after starting in 12th place. Due to racing with a USAC license he was unable to score points in the NASCAR Grand National Series, going unranked (a rule that no longer exists).
