Default Re: The Definitive AU Diff Topic

its been a while ,but my old girl runs 3.89 gear's out of some nissan rear end.its all about your diff and what will fit fit.from memory au's run a 78 borg warner diff and most commo's and nissan gears bolt straight in .both off irs and live axle diffs.if you want 4.11 i think they need to machine something.i remember starting a thread like this years ago or someone else did .??????
