Converting from 2WD to 4WD

[72BigBlockSuprCustom]

Greetings all.

So, I've purchased my first true truck about a year ago. It's a 1972 C-20 Super Custom Camper? Forgive me if I'm a little off on the name. Anyways, I'm slowly putting a little work into it, and I'm thinking that my future plans are to possibly convert it from a 2WD to a 4WD. I've talked to a couple of people, but they keep telling me that I'm better off finding a 4WD chassis instead of trying to convert the current chassis. Currently I'm just brain storming with different ideas of what to do with it, so any input would be great! It's currently running a 396 BB and I believe a T400, neither stock. Of course the truck will not be show quality since I purchased it for the purpose of using it as it's intended to be used for......hauling!

BTW - Great forum.....there seems to be a great group of people in here!
