    Hello,
    I have a 1972 Cevrolet suburban that is stock, with a 350+SM465+NP205, It has 4.10 rear
    gears and running on the freeway for any lenght of time is a pain. So I am looking at swapping
    in a NV4500 to replace the SM465. I thought that GM for a couple of years offered the
    NV4500+NP205 in one ton trucks for a couple of years, but I can't find any referance on line
    to confirm that this is ture and what year trucks they came in. I like the idea of staying with
    as much factory parts, hence the desire for a factory 4500+205. Does anyone know if this
    was a factory combo ? , Also what is the best way to mate the nv4500 to the back of the 350
    with most all the existing clutch linkage ?

    Thanks Mike D.

    The easyist thing for you would be putting and after market Over Drive unit behind the NP205. You could only use the OD in 2wd. But by splitting gears you'd have 8 forward gears and 2 reverse.

    Do a search on the term NV4500. I wrote a pretty decent description of my conversion, the parts needed, and the headaches involved.

    Better yet, I found the thread:
