Yesterday I picked up a set of rear stub shafts from a bug eye Scorpio. Those already have the ABS ring with 48 teeth. The interface for the hub and the bearing carrier are the exact same as on the Cosworth. For the interface for the driveshaft there are 2 versions, one is the 100 mm flange as used on the Cosworth 4x4 and the other is 108 mm, like on the 2wd Cosworth. The Scorpio 24v has the 108 mm and the 4 cilinders have the 100 mm. I'm not sure what the 2.9 12v and 2.5TD have. So using these saves machining your original stub shafts.
