So I have been shaking out my Cummins build, and finally getting to the transfer case linkage/operations. The 1st builder I had for this hacked the ever living something out of the linkage/vacuum shifter(we parted ways soon after once the damage was done), so I am working unfortunately with a bit of a clean slate.
I did a bunch of Googling/site searching so for the next guy trying to dig into this, here is a list of references/links I found;

So as you can see, I have no linkage hooked up to the 2WD/4WD selector(Rotation 1). The questions I have first are observational & operations-focused
- I observed lateral movement with the keyed portion of the selector(denoted 'B') of about 1/4". Is that supposed to do that?
- In the factory set up, does the vacuum motor push and via pivot rotate A or B? I think its B, but just figured I would ask those more experienced on this than me.
Considering that my vacuum system is pretty knackered, I am considering sourcing the correct shift lever either from Ebay or a local pull yard and going with the manual operation 'twin stick' that Rock Laurence has. If I had more of the vacuum system still in place, I would have no issue with getting it going again, but I feel like that ship has sailed considering the $ needed to get it back to spec. I would love opinions and any different ideas.
Thanks in advance.
