Changing my ring gear from course 4.11 to fine 4.11 seems that the old style bolted to the ring gear and new gears need a bolt and nut to hold it to the carrier. Where can I source these? Saw some online for over a hundred bucks thats crazy. Can these be had used? I would assume that I can use the same carrier if not please let me know. For information this a 77 carrier and a used set of gears from an 81 BJ. thanks
