79 k10 rear driveline
 

Just purchased a rough but very fixable 1979 K10. First thing I noticed was that the rear drive line was gone. I figured, ehh no big deal....... apparently unless you want to have one fabricated, it is a big deal!!! Any help would be great. How do you identify the transfer case? The truck appears to have strap yokes on the transfer and the rear end? :smoke::smoke:

Most likely, it's going to be an NP203 or NP205. You can look up the shapes on Google, but the easiest is by the shift pattern.

NP203 is full-time 4wd, so the shift pattern (from top to bottom) is LoLoc, Lo, N, Hi, HiLoc

Np205 is a part-time 4wd, the shift pattern is 4L-N-2H-4H
