Critique my mismatched Teen Build.

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.
