My cab and chassis truck was a 2wd. Driving Daves crewcab before he came and got and having driven 4x4 crew cabs I can tell you the 2 wds turn alot tighter

Nope, Earliest you would find a 32 spline SM465 is 81 and I've parted out a few 81's that had 10 spline.


but before it would fall on it's face if ya put the coals to her and the psi would drop off...I am sorry but the 32 spline started in 85.
And Ryoken I have a couple here.
Figure a cheap way to ship and we can make a deal.

That is not true unless you are only talking one tons.
The one tons started using the 32 spline output SM465 with the NP205 in 1985, the half and three quarter tons started using it with the NP208 in 1981.
Only the one tons used the 10 spline short output shaft SM465 after 1980 (YellowK20 claims to have seen a 1981 with it, I can't say that he hasn't). I used a 1982 K10 for a donor in a 1985 K10 and it definitely had the 32 spline output.

We parted out 3 81 crew cabs that had 10-spline combos all diesels . SledheadAK can verify .
All NP 208/241C's have either 32 ( TH400/4L80E/SM465 )or 27 spline (TH700R4) I've heard rumors of the TH350 being factory mated to a NP208 but I've yet to see one in person EDIT: then there is the 833 O/D 4-speed very very rare only seen two 4x4 versions not sure on spline count as I never separated them but I would guess 27 spline.
off topic a bit, but there was also the 3-spd column ripper in a 4wd configuration in front of a NP205 in the 73-80 trucks I have one of these combos in a bogger project that I stopped progress on when I left New Mexico
Everybody always talks about how interchangeable GM stuff is, trans and t-case combos is definitely not one of them what a royal pain in the dick
Yeah, they were one tons, right?
Yep.
I have cut up a factory TH350/NP208. Most of the TH350/NP208 combos I've come across were aftermarket with the spacer.
All the th350/208's ive seen had the adapter and started life as 700R4 trucks Id be interestes to see a factory setup.

I almost bought a 81 that had a 305, th350/208 in it. Trying to remember why I didnt now. probably the 305.

Ryoken's question of the day....
