Here's the alignment contraption in action. You do camber first. You have to zero the level on the garage floor rght next to the wheel so it zero's out to the floor's angle. There was probably a 1 or 2 degree angle to the floor toward the left side of the garage. So I had to readjust it when I went to the other side of the car.

The reading on the ground is zero (I put the edge of the bubble just below the zero line so It's easier to see). And once it is clamped to the wheel it reads the true reading of 1/4 degree positive for the passenger side.
