This is the reason I take photos with the camera phone prior to taking apart the brakes.
It can be a big help.
Soak everything down with brake cleaner and then take a photo before tearing into it.

AutoZone has an on-line manual with pictures . . . there were two of the pictures that showed exactly what I needed to see . . . they were the only two in the whole section that wouldn't pull up when I clicked on the tumbnails. I finally got it figured out. I kicked myself a half dozen times for not snapping a picture or two before I started taking it apart. I've done a thousand sets of drums brakes in my life (well, maybe just 5 or 6 hundred) but I've only done one set of GM rear brakes in the last 20 years . . . and that was about 4 years ago when I put shoes on this piece of junk. 30 years ago, I could have done this blindfolded . . . but if you don't use it, you loose it.
Also, a good set of brake spring plyers and a one of those handy-dandy spring retainer tools helps make this job A LOT easier. Side two went much quicker! Now . . . just gott'a bleed 'em.
