I am replacing the seat bun for passenger seat on a 2006 X2. I have practically torn the whole thing apart and came to the realization that there has to be a special way to get the seat to slide off the rails so you can get at the screws. The Clymer manual I have shows how to remove the whole seat, but not what I need. I see there are two little arms in the rails but haven't figured anything out. Thanks.

 

There are pressure points on each side rail that you depress that allows the seat to slide up off of the tracks,then the inside rails can be unscrewed from the seat back. OPT
