Re: Did any of the 67-72 K10 4x4s come with a 3-speed manual on column?

Man, that thing is incredible! I guess that solves the 4-speed vs. 3-speed mystery for me. For some reason, I just find the Rockwell transfer cases interesting. I know that a lot of folks out there switch to NP-205's, but there is just a cool factor with the Rockwell's that I can't seem to shake.

I posted this in the 4x4 forum a few months ago, but back in January, I was able to score a NOS Rockwell T-221. It had been sitting in a warehouse since the early 70's and was purchased as part of the entire inventory by a guy in the early 90's. He in turn had it setting in a shed ever since. It still has the cardboard protectors on the splines, and when I cracked open the top of the case, it was pristine inside with the machine marks still visible on the gears.

I would love to be able to see the adapter that sits in between the 3-speed transmission and the Rockwell though. That has to be a very rare thing indeed!

Here are some pics of the NOS Rockwell that I have.
