1966 valiant rear brake shoe removal?

Its been forever....dont you just push in the spring cup and turn the tang 90 so it slides out the slot? Should release the brakes from the backing plate.

Man how is wish it were this set up haha. The ones I have has a spring that’s pushed through the shoe and grabs ahold to a nub that gets pushed in through the backing plate. Definitely was surprised when I saw it haha.
