No matter how good she looks, some other guy is sick and tired of putting up with her crap!

could try to get the third member out of a '87 or older Trooper. but i'm not sure if they have many of those down there in Oz. the rear end on those is the same 10 bolt unit thats in your Luv. i don't know what ratios they had for them though.

If you take the the whole third member, just about anything Isuzu made up to about 87 will have the same basic rear end. The brakes/etc are different on some years, but the diff and such is the same. Ratios vary alot depending on the rig you donor from. Might look at http://www.hotgemini.com and see what they can tell you about those as a possible donor. Being from a car I'd bet the ratio is a bit better for highway top speed/mileage driving.

Troopers (not sure the Aus name for them, MU or Jackaroo I think) pretty much all had 4.56 gearing, which is likely to be worse than what you have now. (At least in the US and prior to 87/88) Another option might be a 5spd trans from something, and I'd look at Holden Gemini stuff again given where you are. I think the shifter is setup a little different but the trans is the same and the shifter could be swapped over.
