I spoke to a mate and he rekons its the wrong diff, the longer bolt is there for a different casing to accomodate 4.11 gears ie bigger pinion?
I'll be pissed :verymad: if its like 3.7 or 3.9 cause i was told it had 4.11 gearing and he knew i was gonna go to 4.3 soon.
I'll have to pull it apart tonight and have a closer look.
