Looking for tech input on adjusting the "play" in the steering box on the 70 project Nova. Steering is definately loose and the front end parts are in good shape. I can move the wheel quite a bit before things start to happen. Checked my 70 service manual and it sounds pretty involved. A lot more than just loosening the jam nut and tightening the worm gear...though I have done that before

Any help and advice would be appreciated. Other than that it runs liked "a raped ape"..
