    It could be done but your going to spend a hell of a lot of time reinventing the wheel. There is several frames for 67-72 trucks here. The rest of the drivetrain they have should work on the older frame. Only thing I don't know about is the actual spring packs may not be the right length.
    I know there is a Burb 4x4 chassis over there. Could make a crew cab with a flat bed on it. I think there is a 4x4 blazer frame as well. I know there are atleast 2 2wd short bed frames there.

    Short answer, the '70 pickup cab will not fit a '77 pickup frame. The problem is the rise in the '77 pickup frame under the cab where the '70 frame is flat until it goes behind the cab then rises.

    It would fit a '73-91 Suburban frame easier though. The Suburban frames are flat until they get past the back seats and rise in front of the rear axle.

    yerah you wil have to make frame changesd because 73-up rear cab nmounts bolt inwards of frame rails and 72-older mount on outside of frame rails and also you cant get to threads for the rear bolts like you can in the 72-older

    then you will have to deal with wheelbase differences too, after cutting alot of rivets in order to swap all body mount brackets except that 72-older beds mounted to frame with brackets and 73-up didnt

    This is what I am doing to put '85 K20 running gear under a '66 GMC 3/4 ton 2wd. The 63-72 frames are all basically the same then they changed in '73. Most of what I am doing was covered by a Peterson's 4wheel and offroad magazine article last year too.
