The fun part of the lev o gauge was trying to pin it at 45 degrees. I know it is basically useless, but so is half the crap I have.

It sounds like you have to pull your t-case, remove the intermediate gear and send the gear to M.R. Automotive in Australia for modification. I'm not sure if the mod is included in the price nor how long it would take.
Emailed them to find out.
Yes, or you can pay for a new gear at $450 AUD that they can supply.

To clarify, they machine the low gear off of the intermediate gear and spline it. The new low gear is press fit onto the modified intermediate gear. As the intermediate gears are quite expensive, normally they want yours to modify in order to keep the costs down.

Last I checked GBR stocks Maxi-Drive low range kits. I've installed about a dozen in the last few years. You have to essentially rebuild the t-box to fit it after grinding material out of the case for the gears to fit. I've been running a 30% kit in my D90 for about 7 years/80K miles. It is a very good product.

I sourced a set of diffs with GBR 4:75 R & Ps and Airlockers in spite of numerous warnings about breaking the gears.
The rumors were right: Definitely noisier and I cracked 4 teeth on the ring gear on the Fordyce trail (didn't know it until Moab). On Cliffhanger I broke all 4 of them off completely.
Went to GBR and Bill fixed me up with 4:71 (20% thicker/stronger) and pinned the ring gear. So far so good.

Made it further than half of the other guys, but the Hammers won.

The new Ashcroft site has a pile of new r&p designs and options you might want to take a look at.

thanks Andrew, we are very pleased with them,

I am aware of every aftermarket rover ring and pinion manufacturer in the world and I can catagorically state these are the strongest,

below is a comparison of the stock 3.54 and the new 3.5 ratio :
