Sloppy steering 65 Cuda..need help..suggestions?

Update: Here is what was wrong. The lower bolt in the power steering box (not the pump) had broken off (and was/is almost impossible tap and remove with an easy out because the frame rails are in a box formation around it, not to mention the starter and the transmission and oil pan make the area impossible to get a drill a the right angle...there is nut welded to the backside of the frame rail) and the top bolt was very loose. So The best way I could repair it (and a friend at a muffler shop helped me) was to weld the power steering box to the frame (which can be removed with a grinder if I ever need to change out the box) and tighten the upper bolt and use some thread lock (blue) and a lock washer to hope it never comes loose again (something I will check on periodically to make sure all is well). THIS DRASTICALLY improved my steering slop problem (as you can imagine) and now I only have about 10-20 degrees or one or two hours on the clock + or - using 12:00 as the steering wheel position going straight down the road.

We also solved our header clearance problem (the sway bar and pitman or idler arm?) rubbed on one of the header pipes as you turned right and accelerated the tourque of the motor would cause the sway bar to rub on the header pipe). We heated it up with a torch and put a nice "dimple" into the header pipe to allow for about 1/2 to 3/4" of clearance. It now clears with no problem.

I have posted some photos in case it helps anyone in the future.

So..problem/mystery solved for now. THanks everyone.
