Steering Box troubles

[340cudaman]

I need some help with a problem I just discovered on my 67 notch steering box. I started to notice some play in my steering, so I thought I'd check the bolts on the box. Sure enough, one bolt was loose. Easy enough, right. When I started to tighten the bolt, I got that "oh crap" feeling when the bolt started to tighten and then nothing. It must be stripped. I was hoping there was a nut on the other side, but it's encased in the K frame. Has anyone else had this problem or any thoughts on a fix?

You may only need to replace the bolt(s). Take that bolt out and see if the loose box has killed the bolt threads. If the steering box was moving all 3 bolts should be replaced , with locktight applied also.
