68 c-10 2wd power steering question

[Nate003]

My steering wheel has play in it from about 10 o' clock to 2 o' clock. when I turn the steering wheel everything is tight up to where the pitman arm connects to that hydrualic ram. I have a 67 parts truck that is the same way, does this mean i need a new pitman arm, or is something wrong with that ram? there is a shield in the way, so i can't see directly what's going on. like i said in the title, it's a 68 c10 2wd power steering. thanks
