To be fair, you should only see those (possibly) on 14 of your 47 machines. I only link them to games I make actual sets for. I know what you are saying about specific parts for games, but if you go through Pinside marketplace, there really aren't a lot of parts, mostly mods, and storefronts with ramps, etc. that you are already finding all over the internet anyways.

I think the days of finding parts for games that are only from a private seller are long gone. I think the best place to find specific parts is in the individual game "club" threads.
