I hear that an off-the-shelf replacement bolt is hard-to-find as the button head diameter is smaller than standard M10X1.5X25. I think the Ford bolt is $12/ea. Many folks have stripped bolts from using impact wrench/electric drills rather than loosening manually with socket wrench, bolt has a loctite equivalent that must break free first. Use an anti-seize when reinstalling, torque isn't too important, beauty ring is just decorative.
