wELL, I've tried to make the Fox VR sensor work, but its designed for other purposes Ford engineers had in mind in the late 70's, not for a roading technician's list of must haves. I was hoping that the 8 plips per revolution reluctor would allow a square wave form logging down to "stop start" walking speed, as required by Autocross Halda, Brantz and other Route position meter. But it doesn't. There are other speedo pickups that do, the Fox system isn't really difficult, but I wanted a truly digital solution. Ford system is half digital, half anologue, and it hasn't helped me.
I had no choice but to set up another Bernstein proximity sensor, and JB Weld/Devcon expoxy in four extra M10 30 mm long set screws with the hex head filled in with a cut down Allen keyhead Arildited to the set screw.
Mr Bernstein, JB Weld, Mr Allen and Mr Tu Pack Araldite® from Selley's Australia saved my life

It was a lot harder, I thought I could just drill four holes, and run an M10 1.5 MM tap and die through it, but there wasn't enough metal to do it.
The requiremnt I have is to be able to log distances of 9-1/2 inches along the road, and with a four stud wheel and 77 inch rollout (loaded) 190/65 390 tire, I can get down to only 19.3 inches with four studs, or 15.5 inches five stud.
I can't fit 10 studs on the inner wheel pitch center diameter, so I'm stuck with 8 3/4" bolt heads on a 108 mm 4-1/4" PCD, and that's going to have to be used when I go Five stud as well.
I'm scratching my head on how to make a 10 bolt even spaced sesnor ring on the back of a five stud brake disk...that's my next project.
Hope this has helped somone here...
