I used everything for a 73, on my project i'm working on, rotors, calipers, pads, banjo bolts, bearings, seals, spindle nut,washer, cotter pins, even those little brake hose clips. everything got it from my local parts house. except the steel braided brake hoses, and spindles, I used CCP drop spindles. They sell them through ebay and if you wait till the weekend they take another 10% off. (at least they use too). it saved a bunch over one of the so called "kits".
did the same for the rear as well bought everything seprate from advance. even the 4 wheel disc M/C. the proportioning valve came from the internet. If you are running rear drum brakes. do a search for PV2 and if you want 4 wheel disc search PV4 you can find the for about $50 or so. I probably have less in my whole brake system then what one front "kit" cost. However Im not running a E-brake so that save some money there.
