Well, Gary's is out of business.

The doors are boarded up and there's a "for lease" sign.
Since I'm in North Phoenix I went to Network Alignment on Cave Creek just N of Thunderbird. Someone had emailed me that recommendation and I found a few references to them on some other 4x4 forums.
I talked to Scott, who had a really nice 70's F150 Custom sitting out front. So obviously he's familiar with our steering systems. He put it up on the rack for me and everything checked out within spec so no charge.
When I asked about my old tires being so worn he said it was probably the toe or worn bushings, not the camber.
Here are my specs just for kicks:
Caster = 2.7 deg left & 3.0 deg right
Camber = 0.9 deg left & 0.7 deg right
Toe = 1/32" left & 1/16" right
Seems like the toe could be a little more, but I really don't get any wander with the new tires so I guess I'll leave it.
