Was reading through the manual last night for my 1976 Gottlieb Royal Flush and there's a diagram of the playfield with all the various parts etc. I noticed that there are posts that look like they can be moved and are labeled con, med, lib. I understand the concept that making outlanes more narrow provides for more liberal (easy) game-play (ie. balls don't drain as easy). The switches can also be adjusted from underneath the playfield. My question is are there additional holes under these posts to move posts further out from their present position? I don't see any on my PF but then again, I haven't taken them off. Does moving these not interfere with the plastics or the rubbers? Just wondering.............

Good to know! Thanks for the tip. I don't actually want to move anything since I think my pin plays well. There are a couple of pins at the outlanes that are missing (holes are there, pins are not). Do they increase/decrease difficulty? I know that during tournaments, posts at the outlanes are often removed to make the ball easier to drain and increase gameplay difficulty. Not sure if these small metal pins do the same. Ball seems to bounce off them when hit directly.
