1968 K2500 power steering conersion???

[BoneSaw]

I'm making progress making the four eyed monster workable. Im installing open knuckle dana 44 with discs and i want to go ahead and convert it to power steering. I have the drag ling on my new axle, and i can buy a power gear box with a 72 pitman arm on it. That should match up fine, my question is mounting the new box. My frame has no dimples, its flat. I have heard varying opinions on whats best and have not been able to get alot of good info for K series. whats the best bracket to use? or a good practice to manipulate the frame. Am i going to need anything else besides a rag joint and ball stud? thanks!!!
