I drew over your pic scott to show what i meant about my arm hitting, maybe its because I'm using the stock steering rack and where the arm attaches is a little higher on mine if you look at the pics.
When the steering is turned left it hits the servo. As i said, maybe its coz my steering rack is higher. Also my servo horn isnt as long as yours.
I mounted my servo on the opposite side and have no problems with clearence etc...
