Automatic tranny conversion

[Gus63]

I am currently interested in converting my original 63 k10 4 speed truck to an automatic. I want to do this, but after thinking about it for a while, it seems like a lot of work. Does anybody have any experience on this matter on a 4wd pickup? What will I have to do as far as the transfer case goes, driveshafts, and just anything else that I would possibly have to do. I am new to this, so really don't have the faintest idea.
