weld it... ive come to this conclusion, the quaife and gripper is no permenant fix.. when you shit a crown gear on a uprated diff you have to buy a new diff and pay to have your uprated internal put in again.... if its not knackered, because of bits of metal from the crown gear, its just too expensive..

i broke my diff last night and i'm just having a tea break right now as i'm half way through geting the diff out.. a mates welding it for me tomorrow morning, so i'll be up lakeside tomorrow night
