8.25 rebuild - Any tech advice?

I'm in the slow process of doing a 73/74 A Body 8.25. Bought a used Grand Cherokee rear disc set-up and am in the process of enlarging the caliper adapter and dust shield to fit the A Body. Bought all brand new GC calipers, e-brake stuff, rotors, etc. Got a good deal on a Sure Grip unit and a set of 3.55s instead of using the 2.71s that came in it originally. Still got to get new bearings rather than use the old stuff. So gonna follow along on this thread too.
