Vee_Que;36975 wroteDiff is cheap to get?
Factory 4.875 is difficult to find, they were only fitted to 79-83 and some later models with a Y series engine.
In any case, I want to get my diff centre rebuilt. I've been quoted 700-1000 depending on what's wrong with it. I just haven't had time to remove the diff centre yet, I haven't properly moved into the shed yet.
