This is a general pic of the underside of the upper right corner of the playfield. You can plainly see the routered holes for a kicker, a pop bumper and switches to register hits. You can also see that the screw holes have been used, and through some of the holes you can see the bottom of the sticker that was placed on top of the playfield to cover the holes up. The coil that is mounted there now is the diverter coil for the Magic Bus.
