Think about how the original steering gear mounts, behind the axle with the Pitman arm hanging down beside the frame rail. When the new gear is mounted forward of the axle, it needs to have a vertical position that allows the drag link to run parallel to the ground, and also parallel to the frame, same as the original drag link but pointing back, not forward. These dimensions needs to be established with weight on the wheels, or at least with the axle at the anticipated ride height.
Some creative bracket fabrication might be necessary to put the steering gear in the right place. Don't forget to consider the swing of the tire and wheel as you decide on where to put the steering gear! On the circle track cars, I like to mock up brackets with 1/2" plywood, and when they fit right, then I duplicate them in steel plate. Plywood is a lot easier to manipulate than steel, and a screwup is less expensive and easier to correct.
