    I have a 1985 C20, 4 speed manual and looking to buy a 1985 K20 with automatic, not sure which trans I''ll use but will the body of the 85' be a direct swap to the 76'? I'm thinking that it is, someone please correct me if I'm wrong and any advice. thanks

    I would tend to think so but not 100% sure. Might have to make a few mods but I wouldn't think it would be to extreme.

    I swapped a 78 onto a 84 frame for a friend once.. no mods needed.. so im guessing it'll be fine..

    If both are 2wd should be straight swap...also if both are 4x4 will be. Hump in the floor different on 4x4 from 2wd.

    the 76 is a 4wd my 85 is a 2wd but has a large hump for the 4 speed manual an already has the cutouts for the TC shifter, the reason for all this potential work is I need the 4x4 and the 76 body is trash, mines not and the 76 4x4 is only $900 running

    after thinking about it for the day, seems I heard someone say the steering boxes are in different places on 2wd than 4wd and did they make a frame change from 1977 to 1978? thanks for any and all help

    Some fairly large mods to switch 2wd to 4wd in those years. Will have to cut change body in center, trans mounts, steering etc. Fair amount of fabrication work. It can all be done, just not a simple swap.

    If your getting a K20 i would go with a 400 turbo. If you put a decent rear end in the truck you will have enough torque to tear down a house as well as good speed :)
