From memory, the seat has 3 adjustment points, seat bottom, seat top and headrest. Two screws attach seat back to floor with 3 or 4 positions available (fore-aft), the seat top position is moved for-aft with right side cable adjustment. Head rest is slid for-aft with several adjustment holes available.
