When you look at where the bleeder valve screws in to the wheel cylinder, there should be two small bolts - one on each side that screw through the backer plate and hold the wheel cylinder in place. Once you remove those bolts (I think they're 10mm) You should be able to push the brake shoes apart at the top enough to get the old wheel cylinder out and put the new one back in. Keep in mind if a bunch of springs and stuff come flying off, your "insurance policy" is the fact that the other wheel is in tact and you can always use that for a "pattern" as to how everything goes. Keep in mind all of the springs on both sides are just the oppisite. What I mean is, don't look at the other one and think of the positioning of everything as "left" and "right", but it'* "front" and "back".
Wheel cylinder - Autozone part number 34054
Here'* a link to a picture of the part:
AutoZone.com | Vehicle Selection | Year
The price listed is $12.99
Funny, the parts that cost $100 are pretty easy to change. It'* the $12.99 parts tha require three trips to the parts store, ruining a pair of pants, breaking three other parts while raplacing, and spending several hours on your back in the dirt.
I guess we pay for it one way or another.
Feel free to e-mail me with any more questions. My first job as a boy was working at a full service gas station in the days where all brakes were drum brakes and all cars occasionally needed carburetor work, and the plugs, points and condenser changed. Were you around in those days? When I pumped the gas into the customers car, cleaned the windshield and always asked, "can I check under your hood Mam/Sir? Those were the days!

I think you'll be able to move things over enough to get the wheel cylinder out though.
