Nylon Flipper Bottom Bearing

Flipper shaft lower nylon bushing, when worn the flipper can drag on playfield! Not good...

There are two bushings for the 1980s flipper assembly:  the upper one (A15529) has a total bushing height of 0.650", and the bottom bushing (A-17565) total height is 0.615".

The A-15529 also has three risers on the mounting holes, whereas the A-17565 mounting holes have no risers.
