66 k10 4x4 disc brake/power steering conversion

[66_k10_manny]

I have a 66 k10 4x4 - Love it!!
But. . .I'd like to install disc brakes in the front and while I'm at it get some power steering.
Is there anyone that has done this conversion?
I've already gotten some tips from other sources. . .I've been told that I have to swap out the front axle with a '73 to '87 chevy. And that my power steering gear box has to come from pre 1980 chevy because after that year they switched to metric threads.
Does any chevy lover out there have any additional info that might help my project go as smoothly as possible?
