[3] The 1959 Daytona 500 had one qualifying race for Convertibles and one for the hardtop Grand National cars.
As NASCAR's only superspeedway in 1957, the inaugural Rebel 300 was held as a Convertible race on May 11, 1957, only to be delayed by rain and raced on the ensuing Sunday (May 12), drawing a fine for promoter Bob Colvin for violating South Carolina blue law (the track's signature fall race, the Southern 500, was held on Labor Day Monday until 1983, when the state waived the Blue Law for 250-mile (402 km) or longer automobile races).
The Rebel 300 would be held as a Confederate Memorial Day Convertible race even after the division ended in 1959, with full Grand National points awarded for three more Convertible division races from 1960–62, won by Joe Weatherly, Fred Lorenzen, and the final Rebel 300 for convertibles on May 12, 1962, won by Nelson Stacy.
From 2005-13, the lineal Rebel stayed on the schedule but was moved to May as a 500-mile race, and in April 2014.
The race ran in September from 2015 to 2020, before a lineage swap of with the newly reinstated Southern 500 weekend in May meant the race returned to its traditional Confederate Memorial Day weekend event in 2021, returning to 400 miles.
