Happy New Year Brandon428,
If I understand you correctly the item in question is the adaptor. I noted two Lowes Kobalt Kits that would supply all the pieces required, unfortunately they no longer seem to be available. As a substitute fix, an off the shelf standard ¼” 6 Point Hex Socket X ¼” drive will get the job done. You may already have what is needed in your tool box but any brand socket will do. Just make the bore for the socket a press fit. The drive bits are readily available.
