Redsy:
If I was the AHJ, under the circumstances, and if there were no "gaps" visable, and the box sides were not visable, it would be accepted.
As another post stated, as a last resort...replace the plate with a "full" one, cut out a piece of the casing, and after the inspection, put it back the way it is now.
BTW, I didn't suggest that....legal stuff ya know.
