I have/had the same size issue where it would not fit on my #2 mirror cap. Had to scrap, dremel, scrap and dremel. As for the target falling through on the #2 mirror alignment part, rotate it 90 degrees and slide in from the side. I cut the targets so each piece has 2 targets on them and rotate over as needed.
