So I was watching a pinball podcast the other day and the guys mentioned a part that I could use...I'm having trouble locating and wonder if a short description might help someone point me in the right direction? I have a pin where someone drilled through the PF and installed a post in between the flippers in order to help with ball saves. Problem is it's not supposed to be there per the original design. The guys on the podcast mentioned a plug that could be put in the hole to cover it up. I'm not having any luck finding it searching the usual parts suppliers. Anybody know what this is called or better yet a place that has them? I suppose I could use filler, but thought this might be a little quicker and easier then that.

Thanks
