Hello- looking to clean up the metal assembly that "receives/seals" the playfield glass as it slid back into the machine- just above the top end of playfield- its a 2 piece "frame" that appears to have some sort of gasket/seal in it. Can anyone post a pic of an intact one/showing the detail of where the seal is and how its positioned? Mine is pretty shredded - if I am going to clean up/polish want to fix and correct that as well. Thanks for the help.
