1970 brake drum removal process

How do you remove the front brake drums on a 1970 Belvedere? I took the wheel off and there are what looks like washers that hold the lug bolts to the drum. Is there a nut under the dust cover that I have to remove to take them off or are the lugs part of the drum or part of the hub? I'm a chevy guy turned mopar and the chevy drums come off with the removal of the wheel. Trying to decide f I'm going to tackle the brake rebuild.
