Refurbing rear 9" drums on my '72 Demon

While driving to put my Demon away for the winter this past winter my right rear brake seized up on me just down the road from my storage garage. Pulled it out this Spring to get it road worthy again and fluid in the master cylinder was low. It's time I took my rear drums apart and refurbish what needs to be refurbished to get a some time out of them before I replace my stock rear end with a beefier 8-3/4".

I've purchased new shoes, hardware kit and rubber brake hose. Not knowing what I'm going to find when I take it apart and believing everything to be 1972 equipment, is there anything else that I should anticipate needing or something I should replace now since I'm going to get into it? I've never done work on drum brakes before but do have a mechanic as a neighbor so I'm not completely lost in the woods.

Any advice is greatly appreciated.
