3.5 ARB Airlocker Help.

Ok here is the story, some very interesting imfo from Daniel :-
Hi Frank,
Always good to hear from you.
We are actually looking into the Paj rear 9.5" quite seriously lately.
That being said, I still can't say it is on "the list" yet, but it's looking more attractive all the time.
Just for your info, here is what we've learned as of late:
1 - The Paj NL type 3.5 litre diff is virtually identical to the NM IRS type diff (NOTE: I only have somebody else's NM measurements to go by - I don't have one to check for myself) except for the fact that the NL has 31 spline shafts and the NM has 33 spline shafts. Could be a noteworthy axle shaft strength upgrade for the NL guys like yourself if you can get somebody to make up some 33 spline shafts.
2 - The Hyundai Terracan ALSO shares the exact same diff as the NL (we did measure the 2 of them up) with the exception that it has 34 spline shafts. (maybe a direct swap-over axle shaft upgrade for the NL?)
3 - The Terracan also shares the same front IFS diff as the NL/NM except it has larger diameter ring gear bolts. We will be issuing a tech brief on drilling out an RD110 to suit. That probably doesn't help you out much, but who knows? There might be a preferable ratio in a Terracan or something that the Mitsu guys would be interested in playing with.
4 - The NL/NM diffs share the same ring gear inside diameter and ring gear bolt pitch circle diameter and number of bolts as the RD46 (3.0 Litre large Mitsu rear) . The only problem is that the inside diameter of the bearings on the NL/NM is 55mm as opposed to the 45mm RD46 bearing journal, and the ring gear bolts are 12mm compared to the RD46 10mm bolts. This therefore opens up possibilities of guys like yourself jumping the gun on ARB committing to build the 3.5 Litre rear and either sleeving the bearing journals or finding a substitute bearing that will adapt an RD46 to an NL. Then you could just get Mark Hardman to wire cut you a custom pair of side gears according to a spline profile that I can generate for him. (Mark and I do this for Tough Truck guys fairly regularly)
That's all I have for now.
If you or anybody you know ever bends or shatters a 31 spline shaft, could you save me the diff spline?
I don't have a 31 spline shaft sample yet, and your diff side gears showed it to be a fairly non-standard profile.
Cheerz,
daniel
I've got a 3.5 V6 axle from an NL I'll give to Daniel to help the cause but what they really need is a rear NM/NP diff centre to play with.
C'mon guys if you want these things to happen we have to help things along (I can't do everything myself).
Can anyone get hold of one of these or at least find a cheap one and a few of us chip in for the cause ?
Frank.
