Our diffs in our Aussie mopars arent what were in US mopars. We had locally manufactured diffs. Lots of our stock type diffs running 9's with a spool and billet axles
come on now!! nobody is run'n 9's with a 7 1/4. the torque of a 9 sec ride would twist the yoke off. not to mention the carnage of the internals from a dead hook.
