Question for owners of Police Force....In the above photo, just to the right of the hole on the playfield which the rod goes through for the microswitch / gate there are two smaller holes (just to the bottom of the middle bumper).  There was nothing there previously and I don't know what should go there?  I believe there is a hole in the 'cocaine' plastic for something there but I'm flying blind...Nothing of value on IPDB either...
