The first thing I would check is to measure from the chassis rail to the outer edge of the spring perch on both sides.
Now some people have reported their spring perch offset is not equal, if this is found to be the case, then less wheel backspace is the easiest and appropriate fix.
Also measure from the inside of the wheel rim to the chassis rail on both sides (vehicle needs to be sitting level when this is done, i.e. both spring heights equal).
If they are different then the 'A' frame alignment would appear to be out. Try correcting the alignment where the 'A' frame bolts to the cross member, but I'm not sure if the later models have the bolt on brackets.
