It made a huge difference for me. The seat was at max hieght all this time. Had to move it forward as my seat was against the bulkhead and the lifted the lever....amazing difference. Don't think I will have to do the floorpan surgery.

My lever did not appear to be doing anything either. My seat was all the way back against the bulkhead. If your seat is that far back the lever does nothing because it rolls back and down. Move the seat forward a couple of inches and when you pull up on the lever....your seat will roll back and down picking up several inches of head room.

Mine's hosed. No matter what I do or where the seat is, nothing happens. I can push or pull on the seat trying to get something going on, but it just doesn't happen. The lever doesn't seem to be releasing whatever it's supposed to release. You can even tell when you try to move the lever... seems like it's binding, not moving whatever it's supposed to move.
