You have to be talking about the Coin Mechs that snap into place and register the correct coin. It channels the coins from the coin slot to the coin box. Also when you push eject button it expels the jammed or incorrect coin into the coin return. These you can get everywhere, Happs, WICO, Ebay, people here will sell them to you, pretty cheap too. It is best to just buy the Coin Mechs, not buy a whole new door. Most coin mechs will fit most doors. Arcade operators will have spares also if you can get to one, they will sell you used ones cheap.
CC stands for Coin Controls. Its the Brand of coin door you have. Again an extremly common coin door.
Hope that helps,
