W123 Alignment

[1983/300CD]

I just replaced the upper control arms, the lower control arm bushings, and the sway bar bushings. Now I need to align it. Sounds like all this work should make it easier to do. Well, I've run into a snag. I don't understand what the eccentric bolts are for if they do nothing toward affecting the camber. My tie rods have stopped adjusting toe. What has happened here, and what do I need to do to fix it? I've rolled it out and back in, and that changed the toe from out to in, but it's still as un-adjustible.
I know some of you have done this before. Am I doing something wrong here?
