Ever have steering that goes crazy at the top end??

Last couple of test-n-tune runs my Duster would start snaking at 100mph+. This is no fun. Was really scary the 1st time because I wasn't expecting it. Tried to tighten up the steering box and took it out again, but same thing. Had to load it up and take it home. Today, I took out the old steering box, and here is what I found: take a look at the mounting holes!

The bolts weren't real tight either.
This is what they are supposed to look like:

Replacing the steering box, coupler, and pitman arm. Already has new ball joints, tie rod ends and spindle bearings. We'll see if this lets it drive straight again.......
