I though it would be simple put it into the casing and bolt it up. no because it sits too deep and catches on the Selector.
so I had this phosphor bronze bush machined up.
If anyone else has a similar casing and wants to fit a neutral light this is what I had machined up.



Same Bush when it's fitted into the casing.

This allowed the sensor to be fitted to the correct depth and work as it should.

With the senso just touching the selector arm when it's in the neutral position.
