rear drum brake removal HELP!

[Dirtkid93]

I have a 1964 chevy c20. right rear brake cylinder blew out on highway ( nothing like using the E brake to drive 2 miles home, also replacing e brake since I burned it) I pulled off wheel, drum wouldn't just slide off, removed smaller 8 bolts and pulled right side axle, was left with what appeared to be a 2 inch bolt with teeth and a 6 sides lock ring that goes in those teeth slots, will someone please tell me how to remove my drum brake, ( with pictures if you can ) before I cut my axle housing and by a new rear end
