    check in the how to section there a big write up on it in there. 3.7's will be a bit harder to find then 3.9's or 3.45's though. you will be fine on highways youll just sit higher in the rev range at 100kmph.

    doesnt make a real big difference, the gears are still the same between solid axle and irs. just makes it a bit simpler to take the diff out

    I'm not 100% sure about this, but I heard someone saying you can order the different ratio diffs that holden make for the overseas model commodores.Might be worth checking out.
