Whats the deal with the right inlane/outlane rubber ring(s)?
The original IJ apparently had a single rubber ring around the two posts at the right side inlane-outlane divider. This single rubber ring basically pulls those two posts toward each other and I decided that over time, this might cause playfield damage at their bases where they mount against the playfield. I decided to always put small rubber bumpers on these posts, one bumper around each post. To me this looks nicer and reduces playfield wear around those posts. I’ve seen older machines (not IJ) where loose posts or posts with stress on them have cut into the playfield and damaged it. It’s up to you what you want to do with that rubber ring(s). My updated rubber-page on my web site accounts for two separate rubber rings there instead of a single ring (which isn’t listed on the rubber page anyways).
