My friend and I are about done (I hope) rebuilding the front end on my 87 GN. New bushings on all control arms. We made a couple boo boos and I would like to know how important it is to correct them. First off, the shims from the drivers side upper arm were put on the passenger side and vice versa. We did put the rear shims on the rears and the fronts on the fronts, however. Then to make matters worse, after torquing everthing to spec, we found one shim fell out from the front upper arm on the passenger side. Can we just call it a day and take the car to be alligned? For what its worth, I compared my two other GN's and the shims were totally different (different number of shims and different thickness) between all three cars!
