    Hello everyone I've searched all over for a NP205 transfer case that I can use. Can someone tell me what exactly I need to ask for look for ect... I have an 85 Blazer with an SM465 and NP208 on it. The tranny is a 32 spline out put shaft, what year NP205 should I look for or ask for and what type of adapter also. I have herd that the TH400 NP205 with the long 32 spline shaft will work is this true? And what adapter do I use to bolt the NP205 to my SM465? Please any INFO will help. Thanks John

    You should be able to use any 85+ 205, the adapter will need to be a 85+ 4spd/205 adapter (don't forget toget the shifter too).

    Thank you for the info but all the junk yards around here tell me there is no such thing as a fine spline NP205 they only know about the coarse 10 spline

    Then they are idiots. :)

    Everything after '85 was fine spline. And how do they explain the Th400 32 splines? Don't listen to those morons.

    32 spline cases ARE harder to find though.

    To clarify for you on the "rarity" of 32 spline 465/205 setups, thats a one ton only application, 1985-1991. You don't see one tons in the wrecking yard very often (if ever) and 4wd ones even less often.

    Private party is the way to go.

    ANY 85+ 205 will work regarless of tranny. The adapters are different but the case and input shafts are all the same after 85.

    Note : the 85+ 205 is identifiable by the round pattern for the adapter as opposed to the figure "8" pattern used on the pre-85 cases.

    Not sure if that is 100% true. I was surprised to find out that my 86 M1031 CUCV has the figure eight bolt pattern still. Maybe just a military oddity. ;)

    No, you need the 465 32 spline adapter, it's 10" long.
