It will be 4wd. I am taking my measurements from a 91 f150 later this week. From there, I have to get busy on drawing it all up on cad, and making the numbers work for the mounting points. I figure it will take me a decent 3 months to get all the parts, and get the steering figured out.
My entire driveline stays. All I use is the Ford 3rd member, and a custom front shaft. MIT in El Cajon can do one for me in a day, maybe two. As far as I'm concered, I might go see the boys @ H&M to see if they have any trick ideas.
