'67 Dart drag car with a rack and pinion swap needs some geometry help

Pic #5 is a good depiction of a bump steer correction, but your problem is probably more in the ackerman. Front steer cars have outer tie rod ends that are outside of the steering axis, whereas rear steer cars have the outer tie rod inside the steering axis. The closer the angle between the steering arm and the tie rod end to 90 degrees, the less the tire will turn. When you turn the steering wheel, the angle changes; one side goes towards 90 degrees; the other side away from 90 degrees. You always want the inside of the turn tire to turn more than the outside. I'm iso a cheap rack for my 66 Dart and my 62 Dart. I bought 95 mustang spindles and rack...but still configuring..
