Wheel cylinder push rods

My Napa store couldn't find them when I called. However, I did find some made by a company in India that also sells parking brake struts and the diamond-shaped washer (retainer plate?) that keeps the shoes on the post. http://www.amazon.com/dp/B000FQ285E/?tag=joeychgo-20 They don't give a vehicle application but they say they fit 10" brakes.
