K-frame alignment?
if you can, get some pics of the LCA and the LCA mount in the K
i think it's been touched on, but a bent LCA pin could throw the whole thing off as well. the same with worn components: sloppy LCA bush, wore *** strut rod bushings could pull the whole thing one way or the other.
you might be fighting a war on several battle fronts too. the classic death by 1000 cuts where a bunch of stuff is just a little out of whack, but stacked together makes everything no bueno.
