I'm working on a Sky Lab and also a Little Chief right now. On the Sky Lab, the rollover buttons get stuck sometimes when the ball goes over them. I removed them from the playfield. When I actuate them by hand, I can feel them sticking. Is there a trick to removing the metal retaining clip on the plastic stem without snapping the stem off? I would like to clean them so they stop sticking.
The Little Chief has two opaque yellow rollovers that don't match what the game had orinally so I will also be changing those. The same metal retaining clip is keeping those in place.
