Hi, I have an AU11 Fairmont 4ltr with the live axle, dose anyone know if AU XR6 IRS diff will bolt into my Fairmont, I'm thinking the Body will have the mounting points for both so I my be able to fit the IRS diff in, but I my be wrong. Thanks

read about someone fitting one into a EF/EL ... and after reading that . . . i'm gunna say no

due to photobucket the pics no longer show

Like Mad says, not gonna happen. You could if you fitted the WHOLE cradle but that is not worth it. Why not try to find an axle to axle XR eries 1 diff? most of those are Slipery Diffs.
