I'm adding coin handling to an S2000, but I don't know exactly how the hopper mounting plate and plug gets installed. Can't find any data anywhere on how it actually is positioned in the base of the cabinet. Can someone post a pic of the mounting plate and how the plug is positioned on the bracket or at least tell me what I'm doing wrong? The hopper I'm installing just doesn't seem to fit in tight and I can't get the coin tray to mount or the door to close easily so something's not right with it. See pic for how I thought it should go.
