4x4 front axle swap

[BigBird05]

I am going to install a 1986 K-10 axle into a 1969 K-10. The 86 axle is the same gear ratio as they 69. I want to get a list of parts that will need to be changed for this swap. I already know I will need the proporsioning valve and disc brake hoses. What about u-joint size? Steering drag link and tie rod ends? Can I use the 69 pitman arm? Does the 86 proportioning valve use the same style brake lines as the 69? How about the shock mount location? What else am I forgetting? I just read that the 86 axle is 3" wider. Is that true? Thanks.
