If you never have seen how to de adjust drums you may find it easiest to grind the heads off the shoe holddown pins. If you look on the back of the backing plate (side closest to the differential) you will see 2 little flat round heads on either side of the backing plate. They are about 1/4"-3/8".
Grind em off and the drums will definatly come off. I have had to do that before on cars where they get real stuck. SPring kits arent very much and I always have a couple of spare pins laying here so I am not too shy of cutting them.
Good Luck.
