I am looking into what it would take to install a aerobatic harness in my Too. Currently I have the shoulder harness tied into the cluster at the tail. The lower straps attach to the rear seat mount. I am thinking about using the seat mount for the non ratcheting strap. As for the ratcheting strap I am thinking about swaging a cable around the crossmember that the seat is attached to. Would this be an appropriate method? I would use a piece of tygon tubing to protect the tube from the cable. The front strap would be wrapped around the seat frame itself.
