Another benefit to using kingpin-style I-beams is that the steering linkage runs behind the beams if you're true to the original Ford design. Ford never dreamed of a steering setup like this one. In place of a steering box, Mark used a Howe rack whose force is supplemented by a ram assist and protected by a Fox steering damper. In addition to protecting the linkage, running the tie rods behind the I-beams puts the rods in compression (better for tie rod end life) and enables a perfect Ackermann angle (better for cornering). The wide-set Toyota frame made it possible to run the steering rack and the swingset inside the frame rails.
