To modify the mounting hole on the sensor, I first removed the metal ring that is molded into the plastic. This ring is there to prevent the sensor body from being crushed when it is bolted down.
I drove the ring out with a punch and hammer. It doesn't take much.
Next I opened up the hole slightly using a dremel tool with a carbide bit. Again, it doesn't take much.
Then I replaced the ring. You can see the amount that I shifted it over (~1mm).
Now it lines up perfectly with the threaded hole on the head.
