Senior Summer conversion. 2wd-4wd

[B.A.R.Tillamook OR]

This is my sixty seven short wide 2wd truck. While I really like it and have been driving it around, I really want 4wd. I found a donor truck, but it only has a ten bolt front end? I dont think it will hold up to 35's and very hard wheeling. Opinions? My truck is trailing arm so there is alot of stuff to change up. The truck is in primer now so I plan on doing final paint while the body is off, I think that will be the easiest way to build my drivetrain and paint the frame. My only big decision is axle choice twelve bolt should be decent in the rear, but I have a friend with a nod. iron nine inch and forty four front with 5.13 he is willing to sell so im thinking about that too. My ideal would be those axles with an nv4500 and reduction transfer case on 4 inches with 35's. Couple of pics of truck in progress, Just built grill out of perf. aluminum yesterday. The blinkers are behind the screen. Built the motor my junior year.
