I have a project where I may use a Ghostbuster's sling magnet. Most magnets on pinball machines have a CNC cutout that the magnet/core sit in so that they are closer to the playfield surface. A picture of the underside of a GBLE appears to show that the sling magnet and core may rest flush with the underside surface with no CNC cutouts in the playfield wood. Can anyone confirm that is the case?
