AU fairmont Ghia V8's 3.23 diff as above

LSD was an option on all non IRS models in AUI but dropped in AUII/AUII when traction control became standard across the range not just in the Ghia.

AUII/AUIII Fairmonts the option for LSD was dropped.

I agree that traction control is the most likely reason as in AUII on traction control became standard across all Fairmonts not just the Ghia.

Here is the AUI brochure on the forum.

I can post up the AUII spec brochure if you want to compare them.

So it sounds feasible for 3.08 small-diffed AU2/3's, at least, that a LSD optioned 3.23 AU1 live-axle diff could be swapped in and the Ring & Pinion changed to one of the other ratios.
