How to make sure steering box doesn't loosen up?

I didn't realize this is supposed to be such a huge problem. In the recent times, I've removed 4 boxes---the one in my 67, the one in the junker 67, and junked out a Demon and Duster. NONE of them had ANY loose bolts on the boxes

In times past, I've never had any bolts loose on the 5 previous Mopars I've owned. My 70 sixpack car had 140K on it when I sold it
