steering box issue???

Hey guys, my 68 barracuda steering has a lot of play, I can turn the wheels with my hand, and when I do turn the steering wheel, the wheel has a lot of play and it knocks when I turn it a certain direction, also the driver wheel sometimes doesn't complete the turn, so I have to turn it by hand, steering box issue???

How are the tie rod ends, pitman arm and the idler arm?
