My No Good Gofers center post broke so I'm looking for the center post that holds the upper playfield up/ hole in one playfield. The one right between the 2 gophers. The post is different than all the rest of the hex posts because it has a little nub on the top of the hex that goes through the upper playfield so you can screw the playfield down without cracking it. It is not listed in my manual and I can't seem to find it anywhere. If anyone has this or knows where I can buy it please let me know. Thanks
