drop or not Transfercase

[Category4performance]

Thanks so much for all the information we build jeeps and clocking the transfer case can solve issues i am not 100% sure about the GM product, As for it being a C or K it was picked up as a cab a chassis. and the VIN shows a CK so if someone can give me a clue on that one. the original owner who is 81 now after a stroke has been to tell me little other than he ordered it withe the steep gears and heavy duty stuff.
