I have these rotors on MoFo and need to change the studs as you can see ......a couple of miles with a loose wheel after some twisty mountainous roads did the damage. The studs are swedged to hold the hub to the hat......the studs are knurled lower down to hold them into the rotor. My question is, if I can find studs with a longer knurled portion and drive it thru both the hat and the hub, will this be enough or do I need to find the right stud and get it swedged again? My problem is I do not know what this rotor came off of, maybe someone recognises it?...long shot I know. It's kinda hard to source the right bits down here in the shakey Isles.
