I'm trying to hook up my steering after many years of downtime, and I got everything straight except the drag link won't adjust anymore to line up to the pitman arm. The steering gear is at high point, dead center at 1.75 turns between the 3.5 turns lock-lock and the flat spot comes up 12o'clock on the input shaft, just like the GM service manual says it should, so thats right. I've rolled the truck forward and it's tracking striaght to so wheels are straight ahead, I've set the toe to spec, and so I go to pop in my drag link, and it won't go any shorter to line up to the pitman arm. I installed that arm like 2 years ago, so I don't remember, does that pitman arm index on the sector shaft? Can you install it any position you want, or is it keyed? I asked because I know it's a bear to get off, so I thought I'd ask before screwing with it.
