I currently have 2 magnets on my prop shaft (well, I should) to read the speed. I've lost these and can't find other magnets as small.
I'm sure I've read somewhere that there is an adapter that goes on the type 9 speed sensor that converts it to an electronic signal so my current dial will read this still.
Does anyone know anything about these or where I might be able to get one.

flea bay to the rescue

Maplins sell them

I am using the built in one on the Mt75.

Very smooth compared to the magnets.

Make sure your speedo can handle a Hall efect sensor before spending the cash.

You can pick the sensor up for pennys from a scrap mondeo.
