I have the 10 splined 205 with adapter for my 465 and a 465 with a 208 behind it. I want to mate the 205 to the 32 splined 465. What parts do I need for this setup and what, if any, machining is required? Thank you for your help /forums/images/graemlins/thumb.gif

I got this information from your website /forums/images/graemlins/bow.gif

<font color="green"> NP205 input conversion kits: </font>
Convert your male input NP205 to a TH400 version 32 spline female input gear. Kit includes new input gear, input bearing and a seal and gasket kit. Requires machine work on the NP205 case to install. Gear bearing and seal and gasket kit also sold separately.
Price - $200.00
<font color="green"> NP205 front output shafts: </font>
Change your weaker 10 spline shaft to a stronger fine spline version in either 30 or 32 spline. Both the 30 and 32 spline are very strong, the practical difference is the 32 spline shaft has more yoke options available.
30 spline front output shaft for NP205 - $160.00
32 spline front output shaft for NP205 - $120.00 (32 spline front output pricing subject to availability, and we don't always have them in stock.)

You need the long 32 spline input and the rare as hens teeth 85-91 SM 465/465 adapter and the crossmember for the round pattern.

Yep, what Tim said is what you need. And I've got just what you're looking for. My price may sound high, but try finding one and getting one cheaper than the boneyards. PM me if interested. /forums/images/graemlins/waytogo.gif
 
He sounds like a nice guy and so far I haven't heard of any complaints.

I realized I forgot to give you the flexplate w/ that tranny when I got home. If you really need it I'll mail it to you along w/ the bracket for the shift linkage to the frame.

Who shimmed that starter anyways? It ate the flywheel! Good thing I was buying a new one anyways /forums/images/graemlins/waytogo.gif
 
There is another way, we have an adapter plate that lets you use the 10 spline adapter housing, the short 32 spline input gear in the 205, and the long 32 spline output shaft in the 465. It's not quite as bolt on as a factory 465/205 setup, but if you have a fig 8 bolt pattern 205, it's all you can do.

Going with the late model method, you have to have the adapter housing, round pattern NP205, and the long input gear in it. Those parts are hard to find.
 
I can get an entire 465 with a 205 attatched from the factory but it's the 10 splined version. I just heard that the 32 splined combo was stronger. I think I'll run my 10 splined 205 and save my money for a factory 465 to 205 32 spline adapter and round pattern 205. I'll just carry spare parts until then (10 splined collar and the tranny to t-case adapter) Thanks for the information, I'll be saving this in thread for later use /forums/images/graemlins/grin.gif

Wish I'd known that 6 months ago, I could have eliminated my 10 spline crap and gone with that instead.
 
I had to bring this up again. Can I bolt the 10 spline adapter to the 32 spline transmission and put a 32 splined input shaft in my 205 (figure 8 pattern)? I have the 32 splined 465 and the 10 splined 205 with adapter already.
 
Yes, you use the 32 spl. output, 10 spline adapter, 32 spline input gear in a fig8 case and our short adapter plate between the 205 and the 10 spline adapter housing.

Whats the price on your adapter plate? I had started to design my own but I bet it would cost more to have one custom made compared to buying from you guys /forums/images/graemlins/thinking.gif
 
What's the purpose of the adapter plate? I thought all SM465's used the same bolt pattern and that it was just the main shaft that had changed. /forums/images/graemlins/dunno.gif
 
To use the short 32 spline input (TH400 version) on the long shaft 32 spline SM465 with the figure 8 adapter (originaly a 10 spline sm465 application) you need an adapter/spacer plate that is about 1" thick for the correct spine engagement (or you could risk cutting off the end of the shaft but it is not advisable).

Basically you are mixing and matching GM parts to get the combo they should have produced from the factory. /forums/images/graemlins/thumb.gif
 
I'm a machinest, a plate like that shouldn't be too hard to fab up but it might be time consuming. How much does ORD charge for the adapter and the input shaft? I'm almost ready to place an order but a price would be helpful so I know if my bank account will be able to handle the charges /forums/images/graemlins/wink.gif
 
ouch! That brings the price up to around $300, and for $300 I could easily find a new style 205 with 32 splines. My wallet hurts already /forums/images/graemlins/doah.gif
 
If you can find a round pattern 205 with the factory 465/205 adapter housing for $300, this kit's definitely not for you.

"I have this really clean '91 crewcab...."
"the farmer next door had this one ton that he just wanted hauled off....."
"I had to pay $300 for it at an auction but somebody had already swapped a cummins into it...."

I think I might have another entry for my list of things I wish would happen to me.
 
You're a funny guy Stephen /forums/images/graemlins/waytogo.gif I'll be placing my order in a few weeks /forums/images/graemlins/deal.gif
