So, it has been a few days into the swap, and there are a couple small problems, mainly being that my hydraulic clutch transmission is 2wd, and I need a 4x4 set up.
Hopefully someone can help me understand that I might be able to swap over the internals from my 4wd cable clutch transmission, to the 2wd hydraulic transmission to get the right set up??

This would solve 99% of my problems considering the PO used a set up that I dont want to try.
I am likely going to use the LSD out of my 2nd gen auto truck. Both are 3.909, and I would rather have it with a manual 5 speed.

Please feel free to let me know your thoughts? After reading the thread on KM132 and KM145 differences, I might be confused a bit. Thanks, Josh
