INSTALLING A POWER STEERING GEAR BOX ON A '71 DEMON........2 QUESTIONS

I was hoping to hear from someone who has done it before. To me, it almost looks like it would be easier to pull the DS lower control arm and torsion bar and pull it out from underneath. I am going to try my OEM box.......If I'm not happy a Borgeson swap may be in my future.......But, my OEM box was good enough in the 80's and I built this car to re-live my youth.
