Finished the clutch project last week, and as expected, the slave cylinder was bad. For the good news, it does not have the dual-mass flywheel, and the flywheel was in good shape. The old clutch wasn't quite worn down to the rivets, but she was due for replacement as well.
For the sorta bad news, the clutch I got for it was the wrong clutch. My truck uses an 11 inch clutch, rather than a 10 inch clutch, which the listings indicated for it. Packed it back off to Rock Auto, and I went down to the local auto parts store for a slightly more expensive 11 inch clutch, which went in without an issue.
The worst problem was a broken aluminum piece on the transfer case shifter, which broke when my mechanic took it out. Not a used one was to be found in the area, and a new one was $264 from the dealer. I took the broken pieces to a welder, who welded it soundly, if a little misaligned. This came back to bite me, it became difficult to get the transfer case into 4L, as the lever was hitting the detent plate before it got into 4L.
I was able to bend the notched plate back a bit to allow the lever to clear. I'm not sure I would use it this way if I had to use 4wd frequently, but it should hold for the few times a year I do use it.
