No.All GM 203 inputs are interchangeable between all three GM versions of the 203.
What Chris said, it's the 205 that needs to have the input bearing hole bored larger for a 32 spline input.

how much did ord screw ya for cus i can get a 32 spline threw 10 spline made by a local machining guy for 130i got dont gunna go junkyard hunting for that 32 spline 203 ive already got a 27 spline 203
the 10 spline on my 465 output is shot to say the least

nope the 203 range box has a larger bore for the 32 spline input.i thought i could use a 27 spline and swap the input..i was wrong.its way bigger.the case has to be machined to fit it.plus if you use a 32 spline 203 you will have to redrill the face for a 208..you can use the rare 203 from a 77 (only year) 465 but iirc that the 10 spline crap.the only thing good there is the rare adapter.im going through all of this right now.gm has to many diffrent cases![]()


ok my 456 had a 208 so its 32s spline...
[FONT=Arial, Helvetica, sans-serif]...the 203s are diffrent.the dodge 23 spline will interchange with a 27 and the 10 spline but THE BORE on the 32 is a large dia than the 27.mabye the cases are diffrent with casting but most 32 spline in fact all ive ever seen have had a larger bore than the 27 spline [/FONT]
All GM 203 inputs are interchangeable between all GM versions.All GM 203 range box castings are the same.The only thing that changes from one version to the next is the input.
So where is this 35 spline shaft coming from because GM doesn't have ANY trans with a 35 spline that i'm aware of?![]()
I'm not sure if this changed when the 32 spline 4wd version was introduced.But there are other (easier) options available

For sure, up to '80 2wd version had a 35 spline tailshaft.I'm not sure if this changed when the 32 spline 4wd version was introduced.
...Then why wouldnt the 32 spline 203 input be the same situation.That has always been my understanding.I have a 10 spline 203 and would be more than happy to mic the input bearing if somebody has a 32 spline 203 to do the same with...

over head in a biss can drive up prices.
if you dont like them go someplace else.
and please dont bash to loud around here like that. thay have good service and parts.
and is your local guy heat treating the item? if not i bet it might wear out 10x faster or worse blow up first hard use.
i have seen some cut aways of heat treated stuff and found the core or center is not hardened like the out side wear the big wear section is.
might want to do a bit more research first before you get that cheep 130 part. and man at 130 he sounds like he might be out of biss soon thats super cheep or he ows you a big favor.

If he's just using the range box on the 203, there's a big huge hole where the range box was bolted onto the rest of the transfer case.
For reference, I think I bought a 10spline rangebox from you a while back and swapped in a 32spline input no sweat.
yes they do the 2wd sm465 is 35 spline
I need a picture of this. I've never seen nor heard of a 35 spline output of any transmission regardless of drive type.
Later,

You need to ask exactly what you are getting for $130.Cuz if hes just gonna cut it down and re spline it,I wouldnt run it.
I have a cherry 465 10 spline output I will sell ya.And I have a cherry 10 spline 203 input to go with it.![]()
