Breeh,

I don't think all 4X4 TH350's were K cases. The original (I think) TH350 in my Suburban was not a K case.

A few years back my TH350 went south on me. Upon teardown, I found that the case was junk. I located another TH350 used in a 2wd with the short tailshaft. I swapped all of the 4X4 guts as well as a rebuild and shift kit into the 2wd case. This setup has survived quite well behind the healthy 388 stroker in my truck.

The 4X4's don't use any tailshaft at all. The main case bolts directly to the transfer case adapter.
