I have a post on 4X4 section too. Looking for a transfer case adapter to go from a th350 to a np205 and anything else i might need. Truck has a sm465 to np205 right now and i am swapping out to a th350. Was told i needed an adapter, power sleeve (coupling), and possibly an input shaft for the 205 cuz it has splines for manual tranny. Any info and if you have any parts for sale would be great. By the way it is a 4x4 tranny that I am putting in.
