It's not the shifters, it's the NP205.......

Yeah mine is an auto TH400 to be exact
I got 400/205 and ord twin stick . does just fine unless I forget and try to shift out of order .

How do you shift out of order? Im curious so i dont do it lol
I have to shift the front axle first, and then the rear axle. I don't have a choice, it won't shift unless I do so.

correctly modified shift rails will still NOT let you do it wrong .
I am just saying if I try and do it out of the correct order .
as in I forget I am in low range and go for the front output and try to go to high . the safety will keep you from doing this .
it just this easy . . . .
front in last and first out before range changes of high or low.

Intersting. I guess at least it wont let you mess up lol.
Ok that makes sense!

So in regards to the 465 mating to the 203...Its obviously better to have a short 32 spline (which youd have to buy) instead of the standard long 32 that came from the factor but im curious to know if anyones actually had a break from having the long 32 spline shaft? I know this makes the assembly and adapter longer, which is never usually a good thing.
Im wondering if ill run into trouble being that i have a 108.5 wheelbase k5 and not some longbed truck to ease the angle of the shorter driveshaft.
Ive seen a few 205 adapters crack...i think its mostly due to the weight of the case and not being fully supported but am i put myself in a risky position by running that long 203 adapter to the 465? I plan on supporting both cases very well so maybe its a non issue?

Never!
Hahaha I just saw some pics of what happens when you break it on the trail. Not fun! The damn 205 is heavy. I can see needing to tie it to the cross member in at least 2 areas.
In your blazer I would definitely do the shortest possible setup.
to give you a idea .
ord doubler plate and 203 range box and 205 is just a tiny bit longer than stock whole 203 tcase input to rear yoke.

I regards to overall length, I run a 465/doubler using the short shaft and factory adapter. I had to go to a CV rear shaft to eliminate the vibration and the riding length is only about 35" long (with the rear axle pushed back 3"). Using the longer 465/208 adapter will add a couple of inches so be ready to buy a fancy CV driveshaft.
I have a long 32 spline SM465 with an NP203/NP205 behind it in a Blazer. I have stretched my wheel base in the front with a zero rate. I have a stock GM crossmember supporting the entire thing with nothing else. I do have a double cardan joint in my rear drive shaft.

Thats what im thinking. Im also thinking that the standard long shaft 32 spline from the 465 is going to hurt. I think the only options with be to buy the short 32 and adapter (or make) from someone like ORD. I guess thats the only option?
Ok that sounds about right. Im seeing short np203 adapters off the back of 465s...Maybe thats because theyre using 10 spline? THey look like factory adapters.
Yes, the factory 465/203 is a 10 spline combo. This is the correct adapter to use with the ORD short shaft.

Ok cool ive gotten that pain over with! I do have to get it reworked when i go to the non slip system but at least the most expensive parts are all there. My shaft is at 34.5" now
Awesome. I have zero rates front and rear, 1.5 in opposite direction on both. That may be the route i go then.

Possibly a dumb question here. Is the 10 spline all that bad? Im thinking its ok but maybe one of those things that youd be a dummy not to do while its all apart...
The problem with the 10 spline set up is spline wear, depending on usage it can be like new or totally shot. Since the 465/203 combo is rare, if you get one with bad wear you can't just run out and grab another (like a 465/205).
The ORD shaft is a cool upgrade but real spendy.

You are way overthinking it. An SM465 with a long 32 spline output shaft, is the same length as a TH400 or a TH700R4. People put doublers behind TH400's and TH700R4's in Blazers, do they not???
