Hey, I'd like a 3.08 LSD diff to fit my XF Wagon. Did anything come with a 3.08 LSD Leaf spring diff from factory? If not, I geuss I'll need to make one. So what do I need here? I'm assuming I'd be able to get away with the following:

2.92 LSD Leaf diff and 3.08 Single pegger crownwheel and pinion?

2.92 Single pegger diff and 3.08 LSD Diff centre?

which would be an easier way to go?
