Alignment - it can't be done?

Did they even try aligning it? Pictures of all four eccentric washers (cams) would let us know if they actually ran out of adjustment. The picture you provided suggest you have all of the adjustment available. If the eccentric washer (cam) was at 90 degrees different (all of the way in or all of the way out) then you would not have any adjustment left and yes they are the only adjusters on a stock suspension other than the tie rod adjusting sleeves which adjust toe. Maybe they are saying they do not have enough adjustment to achieve the the specifications you provided them.
