Makes sense to me... I'd contact Darrin and get his thoughts on it. Spherical Rod Ends are what came on my DT Trackbar, FWIW... (I've also heard them called Johnny Joints or Heim Joints, although I think Heim joints are different).
If all else fails, you could have a "custom" trackbar bent to your specs to clear that Mag Hytec cover, then use the DT ends on it. Adjustment would be a little harder but not impossible, and once it's set, you shouldn't have to worry until time to replace the rod ends.
