These are early prototypes of my hand cast replacement NES Contoller shells, buttons and d-pads. These are hand made, and therefore are not perfect. The included screws are self tapping screws, so be careful nott to overtighten them, and once the threads are tapped, always back the screw out firrst until the threads line up and the screw drops into the threads before tightening, or you risk stripping the threads.

Installation is as easy as six screws
