NASCAR Drivers Who Have Won All 4 Crown Jewel Events

Can you name all of the NASCAR drivers who have won each of the 4 crown jewel races: the Daytona 500, the Coca-Cola 600, the Brickyard 400, and the Southern 500? Please note: the Brickyard 400 first ran in 1994, so while drivers such as Richard Petty, David Pearson, Darrell Waltrip, and Bobby Allison won the 3 crown jewel events of their time, they are being excluded here.
