9 Inch Drum Emergency Brake Parts?

I'm rebuilding the rear brakes on my 64 Barracuda with 9 inch drums. When I bought the car, the rear brakes were totally stripped from the car. I have found springs, shoes, drums and self adjuster hardware, but I have yet to find the emergency brake lever and strut arm; the rectangular spring for the strut arm, the mounting hardware for the lever and the "bat-wing" spacer for the top of the shoes. Does anyone know where I can find these things, new or used?
