Each trim (each side) has 4 studs attached to it and is bolted on. To remove it, it is a tight squeeze and you have to be very carefull not to break any of the studs. When I removed mine, I put the top down and took a small open ended wrench and unbolted it. I forget what size the wrench I used was, but it was small. There is also a screw holding the trim in that is attached to the interior qtr trim near each rear qtr window. Good Luck
