I found a 465/203 at the local junckyard. They want 100.00 for the 203.I`m assuming this is the one I need to double my 465/205 but is it rare enough to justify that kind of price? I know some 203s go for 20.00,or less.What do you think?
 
Didn't that combo only come in one year 1974? I beleive it was 10 spline maybe, sorry has been a while since I looked into all this.

That 10 spline NP203 and adapter is a very rare combo. Only offered for one year and hard to find. If you plan on running a SM465 is is a very decent price from a junkyard. Most out here would be asking $500 or more for it just because it was a transfer case.
 
Buy it now! If it's the 203 alone, you need to check the splines in the input gear, the 10 spline is prone to wear and it could be bad. If that's the case, you might want to pass it up. If it has the adapter with it, it doesn't matter what condition it's in as long as the adapter is in one piece.
 
a bud of mine is paying $250 just for the adater and range box. so for a $100 you gotta deal

If thats the case(prone to wear) wouldnt I just swap out that shaft and use that range box?
 
When you start swapping input gears, any GM 203 will do. The beauty of this deal seems to be getting the adapter housing as part of it. The gearbox may or may not be what you need depending on the condition of the input. But you could always put the new input in that gearbox, that's not a problem.
 
I guess thats what I needed to know. By waiting to ask I missed the deal! /forums/images/graemlins/angryfire.gifSometime in the last 4 days someone decided they needed it more than me. I guess if I ever come across another one I`ll know better and grab it like a pork chop in a boarding house.
 
I got that case after all.When I went there Fri.afternoon the owner said they had sold it,and crushed the Blazer /forums/images/graemlins/yikes.gifit was in.Sat.during a thunderstorm a bud of mine went there and talked to one of the guys in the back.He knew exactly where it was.I got the tranny back for 180.00.True to my word I jumped all over it!With momey being tight I`m now going to start buying a peice at a time till I get it ready to install.Thanks for all the help. /forums/images/graemlins/cool.gif
 
i paid 80 dollars with shipping for my addaptor alone. if it(the 203) has the 10 spline female input on it then go ahead and get it if the splines are not to bad.

Are you guys SURE the 465-203 was only offered for one year? I'm picking up a '79 with that combo for $100 in 2 weeks /forums/images/graemlins/grin.gif
 
As far as I can tell the 465/203 combo was only offered in 1974 & 1975 . I have a GM parts manual that shows part numbers for that set up in 1976 but I have never heard of any 1976 maodel GM truck with it .
It could be possible that somebody swapped the tranny/transfer case out at some point ????
 
I think that yo got a great deal on your 10 spline 203 !
I paid $200.00 for my first 10 spline 203 and made a deal with the seller to only send me the adapter and input gear to save on shipping charges.
I bought a second adapter ( because of how rare they are ) for $75.00 and figured that I would not find another one that cheap ever .
Someone gave me a 27 spline 203 that was in very good shape and that is where I got my range box from.
Both of my 203 adapters came from members on this board ( MJ & Wes ) so keep an eye out for good deals if Ya need a back up parts - they ain't making these parts anymore.....
Anyway - I think that you found a great deal ! /forums/images/graemlins/waytogo.gif

I would definatly like to find a backup adapter,I`ve already broken two 205 adapters,and a 465 output shaft. With the extra lenght,and torque I`ll more than likely be breaking more stuff. /forums/images/graemlins/rolleyes.gif
 
We're working on a new adapter and already have a replacement 32 spl. output for the 465 that will work with the 203 and short adapter. I don't think you'll ever have problems with a 32 spl. shaft out of the trans with a Doubler behind it.
 
The 465/208 combo had a fairly long tail shaft length for the 465 . There is a way to make it work ( look on the ORD web site and it exsplains it all ) .
The 32 spline shaft that Stephen is talking about is the same length as the short 10 spline shaft on the 465/203 & 465/205 combos .
HTH , Tom
 
I see now,it`s the overall lenght that kills it(as the lightbulb comes on over my head).I do want the shortest setup I can get,then I`ll turn my rear springs around to get about three inches back.

Ok, help out the dumb kid here. I have a friend with a 27 spline input 203 he was going to use for a doubler behind a T350. Long story short, that project got scrapped and he offered the 203 to me for free if I'd get it out of his way. I'm wanting to go with a nv4500 in front of a doubler... can I grab his 203 and swap in a 32 spline input? If so where do I find the beast? Thanks! Rich.
