I think the adjustments youre referring to with the A-arm adjust caster and camber. You dont want to adjust that to move the wheel as it will have very undesireable effects. Now Im no expert here, but it seems to me that if your wheel is not sitting in the wheel-well right, it could be that your front end sheet metal could need adjusted from the firewall forward in relation to the subframe. I believe there are ways to adjust the relative positions of the body, the subframe, and the frontend sheet metal. Obviously the other wheel is sitting in the wheel-well better, so it could be that the subframe is sitting just a little off-center in relation to the body/front end. Just my 1½ cents worth. Charlie
