Update: It wasn't the pitman arm - the position was correct. Two different alignment shops told me that there wasn't enough adjustment to straighten my wheel, but I simply adjusted it straight with my tie rod sleeves and approximated my toe-in. The handling is improved. I'm now convinced that the remaining problem IS alignment. I plan to order some firm feel adjustable strut bars and try that. My previous setup had one bar that I had threaded and installed jam nuts on back in highschool(!) to compensate for a wollowed out and haphazardly repaired LCA pivot. Probably the missing link here. Hopefully I won't need to splurge on adjustable UCA's to straighten this out.
