I had the stabilizers Xrayed at the customs this afternoon but could not make a picture. The pivot tube is embedded into a plywood box. There is a rib at the end of it and an anti rotation pin that is inserted inside a hard wood block that is glued to the rib and upper/ lower skin. That looks good to me.
