Conversion Questions

[weedoublewide]

I've been looking for "the truck" for a while and a thought came into my head. Its just a thought that I need itched and who better to come to than the experts =D....

Ive been hooked on the 69/70 body style...its muh fav

So I'm looking for a standard 4x4 vechile, which I am finding are extremely difficult to come by that aren't a complete bucket of rust...

SOO.. that got my little hamster in my head turning on his little wheel.....

I get the 2wd to 4x4 conversion...time consuming but possible...nothing I cant tackle by learning from the mistakes of the many on this glorious website..(thank you by the way lol)

But lets say I got a 2wd standard and then got a donor 4x4 frame (most likely equipped, or was, with an automatic tranny) to swap onto....what will have to be added/modified?

Or is it as simple as taking the standard tranny mounts and swapping it over...
