    Knuckle Stud - larger size needed

    I previously updated the upper knuckle studs on my '78 FJ40 axle to Magnum ARP HD Knuckle Stud (140171-1-KIT); which are M12. I also added a 5th larger bolt. Sadly I managed to strip the knuckle from most of these and now need another repair. I'm running high steer arms. Does anyone know...
