I measured it and got 4.25" spacing but maybe i measured wrong because all i can find for 10" is either 5" or 4.75" or 4.5". Any one have any experience with this setup??
I want to get new rotors, calipers and pads.

================================================
While some newer Fords do use a 5 lug 4.25" bc., there is Good Chance you
are probably measuring wrong.
Because there is
NO Stud 180 degrees across on a 5 lug bc. pattern you
measure the way the picture diagram below shows.
