Sunroof parts fell out of 2002 beetle

I have a couple parts that are broken that fell out that I believe the inner sunroof shade slides across, but I have no idea what they are called, and where I can find them. There are two pieces about 9-12 inches long, wider on one end and narrow on the other end. There are numbers on them, but none of them Bring up results. They say Rockwell international on them.
