A-body idler arms

I noticed the other day on our Demon that we're getting a lot of vertical movement out of the idler arm when the steering wheel is turned. I know already that there is about .025" difference in size between the bushing in the idler arm and the outside diameter of the bolt's shoulder. But at the thread end, we've got about .060" difference. So that much size difference is really amplified at the drag link end of the idler.

Just wondering if anyone else had noticed this on their car and what you've done to fix it. And, yes, the idler arm was brand new this season.

Thanks!
