It's been awhile since I've done a lot of research on the subject, but I think Yota axles are Passenger side drop in the front. Ford Axles are Driver side drop, so it requires an all new t-case, which probably requires a new tranny, which probably requires a new engine.
It just makes things more complicated.
Simplest is the Jeep stuff from what I remember.
My take would be just keep reading through SAS build threads. Whatever you are thinking, it's been done and they'll probably have some good info for you as well.
