Currently the factory manual box sits on top of the frame and the pitman arm mounts to the box vertical instead of horizontal. The drag link runs parallel to the frame to the steering arm. On this cabover, crossover steering is not an option give the axle being used and spring locations.
Mounting a box outside the frame will not allow tire clearance.
My question is are there any power steering boxes that sit mostly on top of the frame with a vertical pitman arm? If so, what applications can I look for?

Any way to put it behind the front wheel on the frame and get a steering shaft to it?
Or does it have to go above the frame about at the front of the front wheel?
Can it mount entirely in front of the front wheel on the frame?
Got a picture of what you have to work with?

There is not much room to move the steering box since the truck is a cab-over and tight. The axle has a tie rod bar that mounts to the rear of the axle, low. I can not tie into the tie rod due to location so that is not an option.
I think the box needs to sit on top of the frame because of spring perch location and tire turning clearance. The Ford F-150 4wd box from 1978 / 1979 is a great option for crossover steering but I can not move the steering arm to the passenger side without heavy duty milling on the passenger side knuckle.
One thought I have, take a chevy truck saginaw box rotate it 90 degrees and mount it on top of the frame instead of on the outside of the frame. make a good bracket and I don't see any reason why that wont work. The tie rod would then swing vertical instead of horizontal.
