Rear Brakes Missing Parts

Help someone please. I have a '75 Dart with 10" rear drums. You wouldn't believe the sutff I have found RIGGED on this car since I bought it. The prior owner is either the world's best red neck or just plain stupid. He sure isn't a mechanic. Wiring ripped out, wipers not hooked up, no temp wire on engine, oil pressure sending unit missing, no horn, no neutral safety switch or back up lights, wrong impedence fuel tank sending unit, wrong size wheels, collasped front end, master cylinder push rod installed backwards and adjusted too long, low brake pedal, and now --- 9" brakes on 10" drums. I love it. I have everything fixed except for the emergency brake spacer bars ( I don't know their proper name) that goes between the shoes and is mounted just below the wheel cylinder. A long bar with a small spring on it. I need both bars and cannot find a source to buy them. I can't even find them in a junk yard. Can somebody please help. The car is drivable now but I would like the emergency brakes to work.
