    I am going to go look at a manual trans and transfer case from a "mid to late 70's 1 ton truck"

    can I get some help on how to ID them for when I head over there?

    It sounds like the t-case might be cast iron, that help any?

    please reply ASAP , I want to go look at it this weekend

    Thanks all

    In those years it will be an SM465/NP205. That is all that was available for a manual trans.

    Pretty durable combination based upon site member feedback. Although the coupler between the transmission and xfer case may require replacement if it's worn.

    If it's a manual it's a 465 no other tranny was offered in the 60's 70's or 80's for the one ton trucks.
    On top of that the 1 ton 205 will have the 1350 yoke, stronger than the 1310 of course and ready for a heavy duty driveshaft if it's where you are heading.
    :D

    not quite true... a few years you could get an SM420......
    it just has the lower first gear. not a bad thing for some of us.
