All steering boxes rotate the same whether mounted inside or outside the frame. Its all about the rotation of the output shaft, how the pitman arm is designed and attached to the output shaft and how the drag link and tie rod work together. Steering boxes can have the pitman arm face forward of the box, face rearward of the box and some even have the pitman arm designed to be 90* to the box.
There are multiple boxes Jeepers use on their Jeeps to compensate for wheelbase change, frame limitations, front axle swap, suspension interference, etc.
