I just finished my swap. I put in new upper an lower ball joints in my 1963 a arms for a 1982 chevrolet truck. I then installed the spindles, disc brakes, brake lines, proportioning valve and steering components on my truck. I had to drill two holes in the passenger frame rail for the late model idler arm, and a hole on each side to run the brake line through. The only line I had to make was a junction from the proportioning valve (mounts up front under the radiator) to the rear brake line. Very simple swap, all parts simply swapped over. My donor parts were in good enough shape that I used everything except the ball joints and master cylinder. My master cylinder is from Car Quest for a 78 chevy truck disc brake non power. Stops great now, was very scary before.....
