Ford stud spacing (4.50") is not the same as GM stud spacing (4.75") - unless they are set up with BOTH sets of holes (10 holes per wheel) or with slotted spacers for studs (which flip-flop), these will NOT fit.

You just need to buy the right lugs and washers. They aren't slotted though which is weird, I think us GM guys got lucky and just any regular shank nut and washer will work. At least that is what I used on them.
They are made to fit both 5x4.5 and 5x4.75 bolt patterns.

The fronts will bolt right on with no issues.
The rears will not fit without a SERIOUS unsafe amount of grinding. I think only one or two people ever ground enough to fit the rears.
To keep a good looking budget setup, most people just run Weld Prostars in the rear, to keep the grinding minimal. Here's my old setup with Greg Weld fronts and Prostar rears.
