Given the age of the Commodore 64GS, and the fact that the plastic used degrades with time and use, people have been finding that the cartridge door have been failing on these units.

These are replacement doors for the Commodore 64GS.

This kit comes complete with TWO cartridge doors, available in many colors.  Metal hardware is not included.  You will re-use the metal bar and spring from your console, and insert them into these doors.
