If you are going to use a Rack and pinion ...then the steering arms on the upright need to be in front of the rack so that the tie rod comes back to the rack and pinion....

In the straight ahead position....the tie rod link and the rack should have a 10*degree angle

So that when the steering is turned to the lock position in either direction the steering arms are lined up with the rack when looking from the top......

Hope I communicated .....
