Thanks guys, you have all been very helpful. I have looked up each and every suggestion. So far the people at
http://firmfeel.com/a_body_mopar_parts.html seem to have a really good rebuild kit for the whole lower assembly. About $1000 in parts to redo all the bushings, ball joints, new steering box etc. A lot of money but a drop in the bucket for me unfortuntley. I think based on all of your advice it would be wise for me to just replace most of those parts for reliability and safety's sake. The last thing on my list to do is brakes (I still have the old drum brakes with single master cylinder).
