I don't have the number you requested, but if looking to figure out the turning radius or diameter, Ford specs list that. You'd have to extrapolate for wheelbase which would get you very close.
If you need the wheel cut angle for some other reason, and can't find it published, you can always use geometry to reverse engineer it from Ford turning diameter specs.
