I did it but dont have a diagram, sorry. However, its an easy swap (IMO) as all you gotta do is procure the brake lines and a couple of brackets/doo dads from the master cyl to the proportioning valve from a late 80s to 93 4wd blazer or s truck.
Clean your new bone yard treasures, swap them for the anti lock unit/lines, bleed brakes, and enjoy.
