Pitman arm is hitting tortion bar! Help?

I tightened up the power steering mouting bolts lastnight..took it down the road about a mile and a half and they were already loose again and the steering box was moving all over...something is deffinatley messed up with this car but i just cant figure it out. I know a new steering box is not going to fix my problem..

Nuts are stripped or spining. It happens. Got to take the box out and look at the nuts in there.

You should be able to see and feel the inner two most steering box nuts from under the K-frame and top next to the motor mount. Tighten the bolts and feel the nuts. The top one near the frame rail you can't get behind.
