Brake drum cracking

Re the triangle washer at the top, pretty sure there is not one for 9" drums (my 64 Valiant). There is one for 10" drums (my 65 Dart). I was kicking myself, assuming I lost parts, even though I very carefully put all in labelled ziplock bags, then found photos on the internet. I have the FSM's, but they might have only shown the 10" drums. I agree w/ the shoe linings. The gomer who rebuilt the brakes messed that up on my Valiant (2 short shoes on one side), which is likely why it pulled to one side. Otherwise, the springs look right, though I don't see the shoe hold-down pins. I vaguely recall an early system which used tapered springs for the hold-downs, which might be in your photo. I put the later self-adjusters on my cars, which I hear is improved. It has a springed hook-arm on the bottom of the adjuster cable. I bought in a "hardware kit" for ~1973 Dart at Autozone. I had to re-use the old shoe pins on my 65 Dart because 1973 pins are longer (wider shoes).
