On many Bally/Williams 90's games, they use a layered flipper ball guide, with two metal layers and the plastic on the top. At the non-flipper end, there's usually one or two screws, with little metal spacers that cover the screw between the playfield and the metal, and the two metal layers. What the heck is the part number or name for that little metal spacer? Can't find it anywhere in the manual.
