    cool thanks /forums/images/graemlins/laugh.gif 77 sure an interesting year for gm trucks, first year for this and for power doors, electric oil pressure, last year for old steering wheel style, only year of yellow side trim, etc

    anyone know of anywhere i can either view pages of GM specs sheets(come with resto packets) for any years from 73-up, or any model lists ?
    i did a bunch of internet searching last night and really didnt find anything at all.

    alldata.com is way wrong:
    http://www.alldata.com/TSB/731152_en.html
    http://www.alldata.com/TSB/701152_en.html

    they funny...

    is this 78 a C or a K ? http://www.donovansusedcars.com/vehicle_pages/169020.htm
    would there be visible 4x4 hubs on a 4x4 dually ?

    1 ton 4x4's were made long before 1977. If you are asking about a 1 ton chevy with an open knuckle dana 60 the answer is 1977.

    No, they were not, except for aftermarket conversions.

    Some assumed you ment only GM. You didn't say that, though, so you are going to get different answers. So what were you asking?

    I used to have a factory GM line-built '59 Chevy 1 ton 4x4 with 9 foot step-side bed. GM did make 1 ton 4x4s (factory line-built) in 1957-1959, but stopped after that until 1977.

    in '57 is when gm started producing 4x4's on their own assembly lines instead of farming out to napco, also marmon-herrington used to do a conversion on the earlier gm's

    They bought the same conversion kit that the public or a GM dealer could and installed it on the line, IIRC. Please correct me if I am wrong, this is what I have read in a few different sources but it wouldn't be the first time they were wrong.

    i believe that is correct, instead of taking the trucks to get converted, they just did it as they were building them, and for what it is worth, i know a guy back in my hometown that had a clean 72ish long bed chevy in his back yard, i tried to buy it from him, but he wouldn't sell, anyway, although i never inspected it up close, he swore up and down it was a one ton when i asked if it was 3/4 ton, next time i am home i should go check it out, always wanted to, just never did /forums/images/graemlins/tongue.gif
