I made the seatbacks quite a while ago, but today I finally got around to making the attachment hardware and fitting them to the plane. I attached the hindge to the seat and fabbed up the adjustment brace for the back of the seat. For the pilot side I expect that the seat will always be in the most rear position. Rather then have the seat rest against F-605 crossmember, I made the adjustment bracket shorter than normal so the most rear position uses the aft position slot.
