Offset ball joint part number?

If your weight was not in the drivers seat, then when you do sit in it, your weight will create a cross-camber difference ; one side plus and other side minus. This change will also tug on the cross-caster. But more importantly, any time the camber changes, then the toe also changes. So if you are more often than not, the sole occupant, then I recommend that you install your bodyweight into the driver's seat. Try it and see. It doesn't take much cross-camber to create a pull.
I chased this around for quite a while until I installed the weight. This is also why,IMO, the 1.03 bars work so well. It seemed to me that they keep the alignment angles in the window better.
