Hehe I know what you are saying, notice my "quotations" from Tom. Thanks for all your help, I had Tom measure the arms on a new CSX he had in the shop. They were as measured from the ball joint to the end of the arm front and back, the tape does not form a perfect parallel ray but it is a place to start.
Front distance: 5 1/2" Rear distance: 5".
