Its hooked in on the side 4 corners. Just push down and squeez inward toward the middle. They should pop right out fairly easy. I beleive you have to take off the top first to have enough room, or its just easier for me that way on mine. The top is the same.
They are a stap to get in and out you should have no troubles, if you have to take the seats out the bolts are under the chassy for the drivers side, and the pass has two in the back you have to get from the top behind the seat with it slid all the way forward and the front two are on top they are visable.
