i will update a few pics I got last week Marc.I was at ford fair since Thursday.

the Scorpio ring won't fit into the 2wd front hub[fits in 4wd hub] but it's marginal so I think a very small machining process would work

the scorpio abs ring could be machined to fit over the 4wd driveshaft

what i measured

blue e46 sensors rear[which should work front and rear on ford hubs with a little spacing

bmw sensor 31mm long 23mm wide
ford sensor front 25mm long 23mm wide

scorpio front abs ring 2wd front 67mm 14.4mm wide
standard 4wd abs ring 70mm diameter and 12.5mm wide
