Before investing in adjustable control arms take it to a GOOD front end shop and have the front cross member bent back to factory specs. Most have sagged during the years to a point shims can't correct. Once the upper A-frame mounts are back in position alignment problems disappear.
I'm not sure if we have a shop around here that would get that involved. Locally we only maybe one shop that still may have that kind skill, the guy is a little grumpy, think "Jerry" and add a very mean disposition.
