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 believe it may be possible to acheive some akerman by moving the rack towards the centerline , at least that is the way I understand it. Notice in this link how they show the wheels on a left turn and angles of them below

I would think you would have to have the tie rod position changed as close to the rotor as possible and move the rack also. And check the wheels on a turning plate with degrees marked to check the angles as the wheel moves.
If you just switched arms from side to side the angles would be way out of wack for sure.
Interesting thread I would like to go to a rack myself.
