I will try to take a photo the weekend.
Mine is also a Stack unit. the sensor picks up on the brake disk mounting bolts. So must be a handy eye to fit it in there. As you know I have given the car a hard time over the years & it has never given problems.
Had a quick look at the front hub last night..... this hole Kev ?
If it lines up with the brake disc bolts I think I can drill it out to take the M12 sensor, or if not use the thread to take a bracket for it.

Yes thats the hole. The sensor (mines a Stack) has a long thread & was the ideal thickness. So a nut at each end.
It picks up directly with the bolts - so ideally drill it out to size.
Did try taking a photo & posting but didnt work, then forgot
