I have a Laser Ball Pin. I have upgraded all three of the flippers to the new style. On the lower right flipper there is/should be a lane change switch or ganged switch. This switch I do not have. With the exact parts/build as show per https://pinside.com/pinball/forum/topic/vids-guide-to-upgradingrebuilding-flippers/page/3#post-773606, What switch (or part number) do I need to correctly fit the new style flippers?
