These directions are confusing me.

1. Always check for loose or worn parts, tire pressure and tire wear.
2. Raise vehicle directly under rear coil springs so suspension is loaded and support
with safety stands. Remove rear wheel assembly.
3. Remove stock rear upper control arm by removing both inner and outer bolts.
4. Adjust the new control arm so the
outer bushing and adjusting nut are threaded
completely into arm with no threads showing.
5.
Hold the outer bushing from turning and unscrew the large 32mm adjusting nut until
the arm length is approximately the same as the stock arm.
6. Install arm onto vehicle using stock bolts and tighten to manufacturers specifications.
Make sure suspension is fully loaded before tightening the bushing bolts.
Caution: While installing the arm be careful not to rotate adjuster nut or outer bushing.
7. Install tire and wheel assembly and lower vehicle.
8. Adjust camber by turning large 32mm adjusting nut until desired camber is reached.
Warning: The gap between the large adjusting nut and the outer end of the arm should
not exceed 12.7mm (1/2). See Fig #1. Exceeding the range of adjustment of these arms
may cause the arm to fail and void warranty.
9. Tighten small pinch bolt and nut to 20 lb-ft. Tighten jamb nut tightly against
adjuster nut.
10. Adjust rear toe, recheck alignment and road test vehicle.
Then there is an illustration which states:
Measurement 'A' must equal Measurement 'B' and neither may exceed 1/2".
How the hell are they supposed to equal each other if the big nut is all the way in, and the length is adjusted by backing out the eye?
Is the "outer bushing" not the same as the "large 32mm adjusting nut"? They are the same. What the hell am I supposed to be unscrewing to get the length close to the same as stock? Which is hard, there are many "settings" with bolts through stock and SPC to line the holes up that allow them to line up on each other.
This pinch bolt setup seems shoddy too. Even tightened down, the larger nut/sleeve is still loose and wobbly in there.
