I will be installing a repro playfield for a Gottlieb's System 1 (Count-Down), and it appears that these ball guide rails are very hard to take out, and in any case are a bit corroded, so I'd like to get new ones. The one I have pulled out so far seems to have a star-pattern base, and I can't recall the playfield for Outer Space (i.e., that I had done a playfield installation a LONG TIME AGO) having this base.
In any case, I'd like to get new ones. The Pinball Resource has GTB-A14571 & A18764 (the boundary between in the outlane & inlane, and the curved part that guides the ball to the flipper) for the System 1 Pinball Pool, and I would imagine that they are the same for Count-Down. However, there are also ball guide rails of 1-1/4" & 2" that are 1/2" high, and 3" that is low (i.e., near the outhole to prevent biffing), and I don't see them listed.
Is there some listing of all the possible ball lane guides?
