You can get a bit more clearance if you snug the threaded spacers that the bottom bolts go through up into the brackets. I had to jiggle mine around a bit but they did come out without removing the bumper. It is a tight fit, though. If I remember correctly I had to turn them 90 degrees before they'd slide out. Removing the grille doesn't make much if any difference but my grille was out when I took out the headlights. Good luck!
