OK.
You wrote above: "For the 4 stud hub you need one from a Sierra with rear disc brakes or one from a Scorpio (1994-1998). For this part it doesn't matter which engine type it is. The Granada mk3 (1986-1994) uses 5 stud, so cannot be used"
My question to this is: These "4 stud hubs" are all the same then? Sierra, regardless of engine, OK but with Cossworth "4 stud hubs" neither?
Thanks
