Quoted from Joniano:My Metallica Premium (metal grille) has similar issues and when it finally sits down in the slots, the left hook is about 1/2 inch raised above the bracket (doesn't seat completely). I can push it down on the left side to where they both sit, but it bounces back up. I've tried setting weights on the left side and leaving it for a day, but it doesn't seem to help. Mine was NIB in Jan. I'm also from Indiana. Could it be a quality control thing with a certain batch? How old is that one?
I've got an issue logged with Stern for this same issue on a IMDN playfield. They haven't responded in a month.... Not looking good.
