Ok. So there's good news and there's bad news.
I took the trans off, because that's easy and quick and fun. With the transmission in 4th gear, spinning the input shaft spun the output shaft. So transmission was not obviously broken.
There was no shrapnel in the bellhousing. Fork arm appeared fine, no bends, moved appropriately.
There was nothing immediately apparent to the naked eye with the clutch that was wrong. I took a clutch alignment tool and put it in there and tried to spin things. Things wouldn't spin. Everything looked fine.
Curly suggests I check the diff, so I check the diff, and the diff doesn't check. Diff is toast. Toast as in I can apply the ebrake, and the input flange freely spins. Da fuq? I blow up a Torsen leaving a stoplight?
Cts-V, OS-Giken, or another 3.9 Torsen, what say ye?

TorsenI/II or Tochigi Fuji Super LSD?
This is much sadness, but fairly easy to diagnose, as you did, and there are plenty of options, as you said.
Still sucks though. Sorry man. Another 3.9 Torsen is probably the EZ button.
