From http://forum.studebakerdriversclub.com/showthread.php?51214-Avanti-ll-Steering-box-Removal Adamderosa steering box removal I just went through this on mine ('72 Avanti II with Ross steering box). I used a pickle fork and separated the control valve from the steering box at the pitman arm shaft. I then tried to wiggle the steering box by itself out the top, but I was unsucessful - it looked like I would have to move the brake booster and possibly the exhaust manifold. Instead I decided to cut away a section of the inner fender - about 4"x6" - and remove the steering box there. After I put the box back in I re-attached the inner fender cut-out with a piece of piano hinge, and now I have a little access door for making the steering box adjustment and accessing the #5 and #7 sparkplugs.
