It looks like your score openings on the backglass are more lined up as you go to the right (facing the bg). I'd take something like a shim or pieces of thick rubber band or something, and shim the lower left side of the bg. You just need to raise it a bit, and that shouldn't affect the right side much, though your credit number looks a little high as well, so if the right side went up a bit, that wouldn't hurt.
