In the pictures above there are 2 rails behind George and one on each side of his shoulders. The ball links that are attached to the front of the canopy frame slide in the rails on each side. (by his Shoulders) and you can see the frame, I built, that goes across with the other 2 ball links that slide in the rear rails. The cylinder is not yet installed in these pictures. It goes between the rear rails, which are covered when the canopy is closed, and all are visible when open. AS per full scale.
