Not Ranked
The early Classic Revival cars used Commodore rear suspension I believe. They have since moved to an AU Falcon IRS.
I've modded my chassis and AU rear suspension to use a Commodore diff center and axles. The Commodore uses the BTR80 center which is a bit bigger than the BRT75 used by the Falcon. There are also a lot more ratios to choose from and I couldn't get 3.9:1 for the Ford rear. I'm also running a Hydratrak LSD.
Quite a few guys have used the Commodore live axle setup under there cars. Not quite as strong as a 9" but still pretty tuff under a light weight Cobra but the whole assembly is a lot lighter.
Cheers
