RS Porsche: I took my seats apart to reupholster them a couple of years back.I wish I had pix but I know someone posted a great series showing how this is done, so do a search. Anyway, IIRC, after you remove the chrome hinge covers, there are bolts holding the seat back to the seat bottom and seat back. Remove them so you can work with the seat back. The seat back cover can then be removed by carefully wiggling it out of the aluminum chrome trim which is riveted to the seat back. With the back off you will of course see the rivets holding the chrome trim in place along with the dozens of rivets that hold the fiberglass seat back to the frame. It is pretty obvious how everything is put together once you get the back off. Good luck!
