Rear Camber Link (inside) Question

[dentmaster]

On my X5 rear shock tower assembly there are 11 holes on each side of the tower for the camber link ball stud to attach to in 3 rows; 4 holes on top, 4 holes in the middle and 3 holes on the bottom.

However, on the X5 set-up sheets there are only 8 possible positions for the camber link ball stud to attach to listed and it seems that position '7' or '8' seem to be most popular. Which positions are '7' & '8' and why is there a difference between the set-up sheet and the physical part?

Cheers
Mark
