Bill I was a ford tech in the 70's I cant rememer how many diffs I set up.
Without the pinnion depth tools the easyest way to set it up is to install
the pinion with the same shims that are in the broken diff. the trick is
pressing the pinion bearing off without damaging it. install carrier set
backlash to .006-.008" apply bluing or even a grease. rotate pinion in
forward direction while holding pressure against ring gear. this gives you
the contact area of the teeth. ideally it should be in the center of the
teeth on the ring gear. The heal of the tooth is the inside the toe is the
outside. if it has toe contact add pinion shim reset backlash and recheck.
exact center contact is not critacle somtimes not even possible. close will
work. I used this techniche when I swithched from a 4.55-1 to a 4.10-1 and
got lucky old shims were perfect. call me if you have any question.Jeff
