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.
I've mentioned that several times in the past. The mount-shaft of the Gen I UCA is even on both sides, while the mount-shaft of the Gen II is very noticeably thicker on one side.
When I first mounted mine, I mounted them with the
thinner side against the frame. Even after cranking the t-bars, I had a very obvious positive camber (i.e., top of the tires leaning out from the truck). I decided to flip the mount-shafts so that the
thicker sides were against the frame. This brought the camber much closer to zero, and I was able to correct it with one shim each side.
It was easy to flip the shafts. I just:
- jacked up the front of the truck, putting it on jack-stands (weight supported at the forward crossmember)
- supported the LCA somewhat with a jack - just enough to take the strain off the UCA mount-shafts
- loosened the mount-bolts for the UCA enough to verify that the shaft could be moved at least with a wrench but wasn't going to pop away from the frame when the nuts and bolts were removed completely (adjusted jack supporting LCA accordingly)
- IIRC, I think I may have even loosened (but not removed) the ball-joint nut connecting the UCA ball-joint to the knuckle
- removed the UCA mount-shaft bolts and used a wrench (and/or perhaps a screwdriver in the bolt-holes) to get the shafts rotated 180?
- reassembled
