I've got some 8' Orbitron parts for free if anyone is interested. I tried to upload pics, but it just hangs and never finishes. All the mesh panels are in great condition, have the ribs and outer ring. The ribs are ok, but some have corrosion where they were in the center hub. When I took it apart the intermediate plate was disintegrated. Tried to get another made but it was too much and couldn't find one locally. I did get one from someone but it was the wrong one. The button hook is there with a Chaparral C/KU on it. It was all working when I got it from another guy in Long Beach, but who knows now. I tossed the actuator as it was not working. have the mount too. A little rusted but still in good shape. Wife has me doing some summer clean up and I agreed it would go. My 6' works well enough for how much I watch. PM me if you're interested. I'm in Palmdale CA.
