P/N Dorman #42002 available at your local auto parts store. $8.99 for qty 2. You’ll need a half inch quality drillbit and don’t forget eye protection. The part will be very hot after drilling so run it under some cold water before handling. I've installed these without the crush gasket and the code cleared just fine.

A viewer asked me how this was done after seeing it on a previous video so I shot this quick explanation.
