I'm interested in taking the differential from a NP 203 ( that allows it to run in 4x4 full time on all pavements) and fit the diferential onto a NP 205.
Is this possible?

No. If you want a big heavy iron case with a differential, just use the 203.
The differential just bolts onto the NP 203. So if I were to make an adapter to bolt it to the NP 205.... maybe it might work.

The NP205 was never designed to be used in such a matter. Besides the 205 is better than a 203 by far anyways, why screw up a bulletproof tcase like that.
The goal here is to be able to use the NP 205 but with the added ability to run it like the full time NP 203.
I would like to have the best of both. 4Hi, 4Low, 4Hi-Lock, 4Low-lock, neutral, 2hi, 2low, 2Hi-lock, 2Low-lock.
4Hi could be run on any pavement. 4-Lock would lock the wheels so that no wheel would spin out.. 50/50.
Having the differential installed from the 203 would allow me to run in 4x4 all the time not worring about drive line binding. I still would have the ability to run it in 2x4 mode and 4x4 lock.
Why reinvent the wheel? Easier to go through the current 203, new bearings, seals and a chain and use it. It will do everything you want to do and have almost exactly the same low range (2.01:1 vs 1.96:1)
That is about the same as trying to take the 5th gear part off of a NV4500 and add it to a SM 465 to gain overdrive.

I would no want to run the NP 203 in full time all the time. I ran the NP 203 with the part time kit bit it eventually killed it.
Just thinking. It may not make much sense. I don't even know it is possible but it would be interestign to try out. Maybe no one has yet.
Why the desire to run 4x4 on dry pavement? Has our recent snowstorm prompted this idea? I ran all over with my 205 in 4hi. You are fine to drive as long as there is snow, slush, gravel, even wet pavement. If you pull into a parking lot and need to make sharp turns or something just throw it back in 2hi. Thats what i did and it works fine.
The "differential" in a 203 was never great for snow driving anyway. I used to drive a 78 k20 in the winter and always just used Hi-Lock. Just Hi range is not really 4x4. It will just send power to the axle with the least traction.

What is this 2wd lock thing? I think you are a little confused as to the operation of the t-case. With the 203, you get full time 4wd (basically an open differential, least traction gets power), 4wd high lock, neutral, and 4wd low open and locked. Locked in works just like 4x4 in a normal part time t-case.
I think you'd be best off just getting an np205 if you don't like the full time of the 203. As said, as long as you aren't running on dry pavement for more then 1/8 mile, you can be locked in. I personally just lock the hubs in if it's possibly going to be bad and only use 4x4 when I need it. I don't like getting a false sense of security with 4x4 in all the time. If I'm sliding around, then I slow down, which helps with stopping.
Sounds like he needs to just get a Doubler if he wants to use all those shift patterns.
I don't know if it still exists but there was a viscous coupler you could bolt on the tail of your 205 that would eliminate the binding but still give you 4wd on pavement.
It wasn't cheap and I don't know if it was just a fad but I will see if I can find it.
