Restoring a coin door and have removed everything on the backside except for the part that holds the orange coin buttons and the part below for ejected coins. Ive removed every screw i can find but those two parts dont want to come off. Are these typically glued on? When I look closely I think I see what looks like glue around parts of the pieces. Just dont want to break anything and after searching havent found answers. The coin door is from a WCS94. Thank you!
