You've gotten plenty of workable ideas already but I'll add more.
You could attach a 'swivel pad' (epoxy or tack weld into a shallow hole or counterbore). Loctite or jam nut the adjuster bolt. The swivel pad provides a spherical joint with backlash in the range of the other options offered. http://www.mcmaster.com/#standard-swivel-pads/=10hxoc0
Another design option is to eliminate the adjuster screw(s)/joint(s) altogether and just slide and clamp the bushing block(s) where desired. Maybe incorporate a scale on the frame to aid location. I have no idea of the range of adjustment you desire but winding a bolt 3 or 4 inches gets to be a PITA quickly. And then there's the adjuster sticking out and getting in the way.
