| Hi,
I have ETB instruments in my Cobra, and use a wheel with holes in it (daisy wheel type) which is bolted to the prop flange and the sensor counts the holes rather than sensing the magnet. Car came like this when I bought it, so I can only presume that this kit was sourced from ETB. No chance of anything coming flying off with this set up, and have never had a problem with it in the four years I have had the car.
Cheers
