nope but will try and explane best i can
all focus's except the rs have a large center bearing on the o/s drive shaft.
now because the rs has an oil cooler fitted to the block the original large bearing mount wont fit so the have a smaller 1 instead.
so after reading about you having a wrc cgi block (lucky tw@t) lol which wil also need the smaller mount meaning unles you can chop down or fabricate a new 1 your going to need a rs inner shaft if that make any sence at all
