Mainjet, if you choose to go with the original steering box, swap out the '37 for a '40 to '46 model. The newer one will fit right in. They changed over to recirculating ball in the newer box so they steer easier then the early box that is just gear to gear. I had one at one time but sold it off cause the truck drove bad, it was the caster angle and not the box, so I am hunting for another one to try. Joe
