Steering box that might be viable for AD trucks with I beams
 

I saw mention of this on the HAMB this morning did a bit of searching and there may be possibilities with it for AD trucks that are running An I beam axle and could be a real problem solver for one with a dropped axle if you used a steering arm similar to what is used with a Ford I beam if it will clear the shock.
It's a Saginaw design box made by Borgeson that bolts to a plate on the frame rail.

The sector shaft goes out below the frame rail and the pitman arm points up helping keep the drag link level.

It's just food for thought and may solve the AD steering box VS exhaust issue with the right exhaust.

if the pitman arm is facing up and you turn the steering wheel right, wont that turn the wheels left? seems like that's what their instructions say.
the rotation of this box will move a pitman arm that is facing up forward toward the front of the car when making a right hand turn of the steering wheel.
