#2 Yes but there can be more than one cause. Isolate the problem. First read up on the steering box service (http://chevy.oldcarmanualproject.com/1929_57chevyparts/57cmpc0539.htm) (http://chevy.oldcarmanualproject.com/booklets/52mts20/index.htm) to get an idea of what internal parts are involved. Second remove the drag link and see if the tightness is still felt when rotating the steering wheel. If it is try adjusting the worm bearing adjuster to remove any shaft play. If no help then jack up the truck and put jack stands under the frame. Grab a wheel and check that there is not restriction making the wheels swing full left and right.

#3 Yes. You can buy one but the shipping is a killer. https://www.classicparts.com/1947-53-Steering-Column-Clamp-Bushing/productinfo/32-306/

#4 ??? Flashlight holder or something like an add-on turnsignal device of some type.
