I have a split seat on my 55.1 which I just received back from the upholsterer. As I don't have any before pictures of how the back was attached to the seat bottom (driver's seat) I don't know what I'm missing to complete the installation. Looking at the factory assembly manual I don't get enough detail to understand if there should be a plate inside the seat bottom, or some type of missing bracket on the outside of the seat bottom to attach the seat back to (see pics).
