It may be too late for this but from what others have said and from what I remember of looking at the set In my garage, the mounting shaft on the gen 2 arms, can be rotated 180 degrees. The thought being that the other side is a little bit thicker from the center axis making it easier to get the proper camber without the need for adding as many shimms. Maybe Tag or captn' can chime in on this one.
