Cool stuff with the cam sensor - I have one of those sensors and brackets for sale (Oddkidd ones) if anyone's interested
Cheers,
Andy
P.S. I think the brackets were standard fit on some Lancia's (Delta?). I found that with a fixed bracket the Cam sensor would move too far from the phase disc and cause the ECU to go into limp home mode (e.g. when going over a big bump in the road). The spring setup keeps it within range and uses a Weber Marelli CPS
