Does the sm465 by itself have a 10 or 32 spline output? If it has a 10, you cant buy a 10 spline input gear for the 208.

I also had a Rockwell blow up on me, I would say go with the 208. You dont really hear about them crapping out unless the case itself breaks.

If you plan on doing hardcore wheeling, however, I wouldn't run either. Go NP205 and dont look back.

I have two 10 spline SM-465's and Rockwell T221's sitting in my shop, and (at the time) a 32 spline SM-465. The SM465/T221 actually belong to a good friend of mine, but he said I could use one set up if I wanted to. He bought them when he was acquiring parts for his 63 chevy truck. His project is converting the 63 to a 4x4. Along the way he acquired a divorce mount NP-205 and I came across a 2wd NV-3500. Now the plan is, my friend is going to use the NV-3500/NP-205 in his 63.

I ended up using the 32 spline SM-465 and adapted my NP-208 for the project...had to change out the input gear. I did have the NP-208 blow apart on me. I came across a set of 33's and I was mainly after the wheels, but the tires had a little life left on them so I used them. The tires needed balancing so I had that done, but it didn't last. They got out of balance again which caused something to bind up and got the Burb in 4wd. I didn't make it home in time and the chain snapped and took out part of the case. Similar situation happened on the 2nd transfer case, but fortunately it didn't break.

Right now I am waint for a UPS to deliver my Warn Premium hubs so I can replace the autolocking hubs. I will also have a newer set of tires put on the Burb before I drive it again.
