For the bearing/hub carrier you need one from a car with 253 mm discs, vented or solid doesn't matter. All Sierra's, Granada mk3 (1986-1994) and Scorpio (1994-1998) have those, except for the Sierra Cosworth and Granada 24v (Cosworth) and Scorpio 24v (Cosworth).

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.
