Thanks, but I don't think this answers my question. The alignment had been done using different thickness shims from front bolt hole to rear bolt hole, between control arm and frame to adj caster in the past, so it can be physically done but is it ok to do so? and does it drastically change the ratio of caster from stock setup?

This method of shimming is the only way anyplace will do it and I already wasted money at sears and they really screwed it up. Maybe the stealership will do it right but I doubt it, going to try I guess.

You say add negative caster but specs is 2,57+/-30'. do I subtract or add to this number because it appears to be positive?
