Finally got one rear brake assembled. There was much gnashing of teeth and swearing. Here is the procedure:

Get the parts together. Lubricate and assemble the adjusting ring.
Slide the big spring that goes on the bottom between the hub and the brake actuator.
Hook in both sides of the big spring into the bottom holes into each shoe.
Attach the top spring into the top hole of each shoe.
Using great force and pull the power of the gods, pull the bottom of each shoe so it sits on the correct spot of the actuator. I used a hook.
Put the adjustment screw into the top part of each shoe. Some force is needed but not as badly as the bottom part.
Align the shoes so the center holes of each shoe are aligned with the hole in the dust cover.
Using needle nose pliers push in the retaining spring through the center hole into the hole in the dust cover. Once pressed in turn one quarter turn to engage the hook.
You are done. If you cut yourself or injury yourself in the process, be satisfied you have sacrificed to the gods and they will smile on your repair.
