You got it. Just put drop springs in rear. Some people say they get away with no C notch on a 6 inch drop but I think most do c notch the frame after 4 inch to keep the axle from hitting frame. On the front you don't want too much drop spring. You nailed it: 2 inch spindles and 2 inch springs. Your disk brakes on front are common on 71-72 trucks so you won't have any problem finding spindles. Try searching this site or use Google and click on the posts for this site.
