Get a Haynes manual. They have a pretty good write-up/photos of the drum brakes from that era of Ford. Heck, I used my truck Haynes manual to do the rear shoes/cylinders on my buddy's '88 Crown Vic. Like holland501 said, do one side at a time, and give yourself someplace to lay out the parts as you take them off--arrange them more or less as to where they go. Brake parts cleaner rocks. The springs can be a little tricky, but needlenose pliers help reinstall them.
