XF Rear axle/diff drum or disc brakes question
I am going to put a 3:23:1 ratio diff on my XF in the next two weeks, mine is 4 wheel disk brakes, and what I was wondering, when I source a diff, can it be from a drum brake diff? are the master cylinders different on disc and drum brakes? e.g. will I have to use a disc brake diff or can I use a drum brake diff if I find one? I remember a post about it, and I think XD/XE/XF were the same, so you cna swap them around. I just want to keep it disc brakes at the back, too much mucking around switching.
Anyone done it before? Any help would be greatly appreciated.
