The number is a bit hard to read since the 3rd digit is double stamped on each other. So I beleive my case number is 028, pre-ordered from AA by Mudrak very early on. It sat around in the garage unassembled for a very long time. I followed Poser's threads on the Orion very closely and finally built it up with all the latest upgrades from AA which included: the back-cut gear, stepped thrust washers, I also used brand new Toyota shifting colar...
The only problem I had was shifting difficulties with the AA supplied brass nut and spring. It was impossible to shift, I tried different washers and did not help much. So I went back to the Toyota spring which I bought brand new from Toyota and the orginal headless screw so I can adjust the tension on the spring.
The Orion/H41 combo gives me about 80:1...Very sweet



and looks just like stock
And I would to thank Poser for all his efforts

and Mudrak for the case.
Edit: Add a pic:
UPDATE: Took the truck with H41/Orion combo through the 2008 Rubithon, the low gear combination is awesome!!! Many times, I was in 2nd gear, the 1st is great for tricky situation. We also spend 10 hours driving toward and and back from trail heads. So far no popping out of either high or low. In an earlier Rubithon my spotter told me to show down when I was idling (with the H41/3spd transfercase), this time Mudrak as a spotter told me to hurry up going up a major obstacle on Cadilac Hill
