Is there a part number for cockpit side panels that protect the sliding windows?

Does anyone have the part numbers? I've gone through the parts catalog and no luck and no diagrams that I could find. I've also scoured the internet, the Ercoupe Tech Group, Univair, Aircraft Spruce and the wild wild web with no luck. I wanted to look them up to see what they cost then weigh with the labor to clean and fix the current ones. They are in a bit of rough shape but can be salvaged at a couple - three hours of labor possibly.
