Best way to turn my C-20 into a K-20?

    Hey guys!

    Since I sold my K-10, I'm now without a 4WD vehicle. I don't do any off-roading, but I need something with 4WD for winter time use and for muddy conditions. I pull a cargo trailer for my business, and sometimes I get into customer's yards and get stuck.

    What I would like to do is put IFS under the front of my '81. I know, I know, but I want a smooth riding vehicle. Since I'm not planning to do any off-roading, I thought the IFS would be the best of both worlds...good ride and 4WD.

    Another option is to put a straight axle under the front. I didn't like the ride that the straight axle had in my K-10....it rode worse than my 3/4 ton!

    The third option is to get a rolling 4x4 chassis and swap cab and bed over. This would probably be the easiest.

    I don't want to trade trucks. I love my '81. I've got it set up just where I want it. It runs great, has a strong 700R4 in it, has all the goodies like rear air springs, keyless entry, aux. fuel tank, CD player, etc. etc. I don't want to have to swap out all that stuff.

    Has anyone tried to put IFS under an older truck?

    Thanks for the help ya'll.

    Go rolling chasis, it is the easiest and most reliable... Plus, you can choose what axles you want!

    I haven't done it but I did think about it.
    I am in the process of doing the design.
    I go off road a lot, and I wouldn't be building this for myself, but inventing and fabricating is in my blood, and I want to do this, maybe next summer I would have all the wrinkles worked out and start making it.
    It can be done with the late 80' early 90's components.
    You will need some welding and probably a donor truck, but it will be perfect for what you need.
