Transfer Case Swap

Can I replace the NP203 with an NP205 in my 76 K-20 It has a 350 engine and TH350 auto transmission, if so what will I need in addition to the case and shifter. The truck has manual hubs I suspect it has been modified to part time, it makes a knocking noise when in low range I am afraid the case needs replaced.
Thanks for your help:)

best way to do this swap is get a doner truck with the desired t case and swap trans, tcase and drive shafts

cheaper and just as good have the 203 rebuilt unless you are into some realy serious 4 wheelin a rebuilt 203 is just fine
