A Body Rack and Pinion Converison

Ok I understand the general pricipals involved. What I dont quite picture is how in the world would you get the tie rod end outside the balljoint center ( front steer ) without getting into the wheel or tire. Also,, The center line of the ball joints reletive to the center line of the rack. What would result from moving the rack further forward of the ball joints, other than more angle in the tierods ?
I sure wish I had something else to drive. The spool mount small block K for this project is in use :(
I do appreciate the responces and that link guys.
