Rear Drum Brake Help

Whoever did the last brake service should not be allowed to even put gas in a car.
Virtually everything is wrong, missing, installed incorrectly. 2 secondary shoes, hold down springs, return springs improper installed, self adjuste cable guide in wrong place, wheel cylinder also leaking. I would bet that the drum are also over machine to specs.
Here is a photo of what it should look like.
Get out your Factory Service Manual and most of your future questions will be answered.
Strip it to the backing plates and replace everything, might need to also service the rear wheel bearings
