    cab mounting is the same, all body stuf should swap over. Only thing that is different is the trans tunnel, the 2wd body won't have the hole for the transfer case shifter.

    the hump of the tunnel is higher on a 4wd if I recall. been along time since I did that swap. alot of the 4wd's had a bolt in hump. You can swap that right in and cut away the sheetmetal you don't need.

    4 speed trucks have the tall hump. Auto trucks are different. Maybe a little more than moving tunnel plates over. You could add a small body lift (1-2") to clear transfer case and/or lower case a little.

    Nope. 73-80 frames and 81-87 have their own sets of bushings though. You need to use the bushings appropriate for your frame.

    you need to do a min 1.5 " body lift due to the lesser arch of the center hump in the cab body
    i allways do 2" as they sellthe kit like that
    or be cheep and buy the 3" kit and cut all the blocks in 1/2 and save for the next 1 or sell cheep 2 help out some 1 else

    I have done this. I could only find a 2 wheel drive cab for my truck. I had to cut a hole in the floor where the transfer case shifter goes. I went with a 3in body lift 'cause the way I measured it was about the difference between the two. Mybe it is 2in I don't know for sure. Other than that the swap is straight foward I had no problems.
