C10 2wd to 4wd help

[NorrisC10]

Hey all new to this site just bought a 1970 C10 not too long ago. No rush in doing so but I would like to do a 4wd conversion in the near future and trying to get any helpful input. I looked through some of the builds and they are helpful but though I would post up and ask for myself, but if anyone has any great build links (That i may have missed) they could shoot over that would be cool.

but back to the truck it is a 1970 C10 coil springs all around. I have a 14 bolt rear end, 10 bolt front axle, and a np203. I have a welder and enough fabrication skills to weld up any brackets, etc

I know that it would be easier to buy a 4wd frame and convert everything over but I would like to do it using my existing frame. Maybe 4 link the front and rear? I have the heim joints and extra dom tubing laying around.

But any input is much appreciated.
Thanks
