Morning everyone, on the 1968 FJ55 it appears they used something different than the steel brace mounted to the wheel hump that supports the rear seat upper section. Mine has a steel arm attached to the seat back and a plastic roller at the end. When the seat is up it goes into a small bracket to support the back. The parts book only goes back to 3/69, so it doesnt show that type of brace. Does anyone have a part number for the plastic roller?
