Also you will have to unclamp the seatframe from the seat adjustment cables. There's a clamp that bolts to the cable in the middle of each side. The fore and aft seat adjuster in 49s only latches on the driver side. Both sides clamp to a cable that keeps them parallel running back and forth. If you decide to replace the cable (apparently you can get one with clamping at Home Depot), be sure it crosses along the back so that the outside cables left and right move in the same direction.
