I recently swapped a 1990 12v cummings with Torqueflite 727 2wd into my 1972 Chevy K10 4x4 with NP205 transfer case. I want to keep the 4wd and NP205 transfer case. What all do I need to mate these 2 together? i read i need a coupler with the different spline threads and a 4x4 tail shaft. Is that all i need and does anyone know where to buy these parts? Any info or help would be appreciated. Thanks

 

Welcome to the forum, is your chevy transfer case married or non married? If it is non married you would need the yoke for the 727 tranny then build a shorty drive shaft to fit between the 2. If it is the married style you would need more than just the 4x4 tailshaft as the mainshaft in 2 wheel drive and 4 wheel drive are different and you would be better off getting a 4x4 tranny imho.
