I have the AA x-member, I don't know if it's me or the way it's designed but I can't seem to get it to seal right. And the way it mounts on the PS under the seat tank is a bitch. Other than that is seems solid.

Rusty, on the AA crossmember if you have the one with a welded in cone it will leak.
If you have one that uses the original cone cover on top of the crossmember you can drill a hole to let the oil drain back into t-case. Check out the stock cone and you will see the little return channel and if you look at t-case you will see the return hole. Use the cone as template to locate hole on AA crossmember and drill a 3/16 hole. Stopped all leaks from the cone on numerous rigs where we found the hole was neglected on original install.

I didn'tt have room to use the studs without a lot of cutting on the floor pan.AA crossmember....
If you use studs instead of bolts it will seal and not leak...new or old style, does not matter.
Why would that make a diffference??

The stud and nut fastener stays secure....the bolts work loose.
I have replaced bolts that were used with this style adapter, that were leaking, with studs and the adapter stays secure to the rear of the case and does not leak.
Red locktite is your friend.

Looks like I will need to pull the tranny tunnel and crossmember, againThe stud and nut fastener stays secure....the bolts work loose.

Case #31
4:1 ratio
Has the retrofit parts (undercut hs gear, shift rail, shoulder washers). I held off building it until AA came up with a solution.
No problems so far.

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.

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

Just got the case put in. It is number 398, 4:1, and it has the thrust washers. I had the case built my my local shop, "Olympic Offroad." I also just put in a non us, stock trans with the compound low (4.95, what kind of ratio does this mean i have?). At first it had very hard shifting from low to high however it is getting much better. No problams yet, works well.
Case # 327
4:1 No problems w/ the orion at all. However I did snap the spud shaft like a pretzel. Its the AA adapter shaft for 16 spline to NV4500 trans. AA warrantied it and gave me the 10 spline shaft and gear,bearing etc. to convert to 10 sline . they said it was stronger?

Interesting! I'm running an SM420 with the AA ten spline spud to a 2.31 geared 4-speed case - have been wondering how strong that link was - but I was thinking more about the adapter, not the spud shaft. Good to see the adapter can take a beating
.
Hopefully the 10 spline is stronger, the 16 spline spud shaft snapped easy - way too easy I'll attach photo (maybe first time)
I have 37s but still running stock front axle shafts, they should have broke first IMO

Bobby long makes a new shaft as well that is Cro mo. Just another option. I am very surprised that you haven't broke your from axle, mine went as soon as i put 35's on. good luck
I've had the ten spline in for over 6 years - it's been thru a couple of stock birfs, stock rear axles, a chromo rear axle and 4 pinions due to bad axle wrap - and a few lock right small pins...oveall, just a lot of abuse. Guess it's the difference with the 4-1 gearset?
just saw the broken spud. i've broken two. sbc-nv4500-orion-arb-38's. i was probably a little rough on it.
Number 408 is going in soon--hopefully next weekend if I get finished rebuilding the transmission by then. I built the orion with a new mainshaft and hi/low shift collar. The stock thrust washers gave me the correct end play(.009). I'll edit this post when I get some miles and wheeling on it.
Edit 1: After the first ride, I am disappointed. It pops out of low range on steep downhills.

I have Orion #084 on the back of a SM465
The Orion was built and installed on my 465 by Steve Cramer A.K.A "Poser"
It is in a 71 FJ40 powered by a Chev 292 I6 with a 38 Weber. I am running 4.1 gears and 35X12.5
Interco's.
Works great, gives me a good road speed and a hell of a crawl ratio
