I am doing the rear disc conversion on my frame-off. I have a 72 K20 and am thinking I can use the front brake hoses for the rear calipers. There is a hole in the rear part of the frame, above the rear tire, just about where it is in relation to the front setup. The hose will go into the same spot, and this would eliminate running the center hose down over the differential like in the stock setup. I know this would require 2 hoses (one for each side) instead of the 1 in the middle, but would look cleaner, and keep the lines off of the diffrential. Just wondering if anyone has done this before?
