SM465 T221 to NP205

I am looking to manual swap my Suburban and the Current deal I am working on is an SM465 with Rockwell T221. Would my NP205 bolt up to the SM465 inplace of the T221?

221 isn't divorced?

Nope the T221 bolts to the back of the SM465.

Re: SM465 T221 to NP205

You'll need the NP205's adapter. My truck had a carrier bearing for the two piece driveshaft that had to be mounted in a different location since the rear output for the NP205 is not at the same height as the T221. I also had to modify how the crossmember sat.

Here is a link to info on my swap.

Re: SM465 T221 to NP205

Infinite, which 205 do you have, or off what truck, trans and year?
Bolt pattern and input spline count?
I'd start researching the spline count and shaft orientation on the T221 to see how similar or different than it is to your 205.
pirate4x4.com can be a good place to get parts (like the TC adapter) but don't talk too much over there if you're sensitive. They can be harsh...
