Dude, this is one of those jobs I might farm out next time. Or maybe I'll just put disks back there.
take your time. and do one side at a time
get a set of brake wrenches.
Take pictures of how all of the springs are oriented
Clean off all the parts ans backing plate with Brake clean
Spray the bleeder screw with PB baster and only use a brake line wrench on it
put lithium grease on the pas on the backing plate where the shoes touch and the screw portion of star wheel
There is a primary and secondary shoe- one is larger. primary is shorter and goes to the front
If your car has a lot of miles on it- spend the money and get a new brake spring kit
Dont spend the money to turn the drum- just get a new one
Inspect the wheel cylinder and if you see any leaks replace it
When you adjust the drag on the start adjuster the drum should just fit over the shoees and adust it so the shoes just start to drag on the drum.
