The mechanical stop still has to allow the seat to go far enough back so you can actually physically get into the seat which works OK if you are 6 feet or taller. If you are a 5 foot 2 women then the stop will allow the seat to go far enough back you can't reach any of the flight controls.
The latest mod uses a fabric strap and an inertial reel. This allows full for and aft travel of the seat under normal operation but will instantly lock under sudden movement ensuring that no appreciable uncommanded seat movement can occur.
It is IMO the only acceptable mod to address the long standing issue of unwanted seat movement and since Cessna will give you the parts for free and pay for the labour to install it any owner that does not fit it is IMO stupid.
