You are right about that unless they have an OLD parts guy!
Ok I broke out my shop manual. There should still be some type of hold down in the center of the shoe. It may just be a spring. However there shoud be a removable clip on the linkage conecting to the shoe. But I am getting ahead of myself. You should have already removed all the return springs thus freeing up the top of the shoes. Then go half way down the shoe and remove the "hold down spring" and this should allow the shoes to be pulled away from the WC. Once you get to this point you should be able to remove the shoes and linkage off of the anchor pin. The linkage can then be removed from the shoes by prying off the clips holding the articulating link pins.
I hope that this helps.
Goodluck
