Just to fill in the gaps for you mate, the track rod end in the drop arm is a lot easier to get off than the drop arm, wind the steering full lock in whichever direction to point the joint where you can access it. If you haven't got a balljoint splitter, place your heaviest hammer against one side of the eye on the drop arm and hit the opposite side of the eye with another hammer as smartly as you can and it should pop out.
You can't get the column out just by removing the clamp bolt, but you can if you remove the four little bolts that hold that flange onto the steering box, you can unwind the whole column from the box and remove it, as long as the upper bracket is removed. IMPORTANT keep the steering wheel fully on if you do this or the ball bearings will all fall out in the steering box and everywhere else. Also, the top of the steering box will be open to dirt getting in etc so leave this till the bulkhead is off (if you even needed to). The steering box is quite simple inside by the way and is worth opening up to inspect the screw and bearings.
If I was where you're at now I would be disconnecting track rod, then bulkhead brackets, at top or bottom, probably bottom, then removing (if nothing else left). Then looking at removing steering box when it's off the truck.
