In the French airplanes, this type of junction is a rubber species that if compresses and strains as the movement, however, in the MIG-21, is used same metal plates.
Using aluminum plates, I cut three parts that, glue in the related junctions, act as if they were the originals (the functioning was similar). They confer in the photos to follow.
