I was thinking of a steel sleeve made out of a grade 8 bolt, the smooth shoulder part with a pilot hole that would move from hole to hole as each one was being drilled. 1/2" steel sleeve, 1/4" pilot hole in it, hold sleeve with vise grips to keep sleeve from spinning and ruining the template. Then remove template and enlarge the holes to accept the stock Ford lug/stud splined shoulder. Does this sound workable?
