How do you go about removing the back seat (The part your back is against when seated)? I looked but all the bolts seem to be non accessible... maybe I am just missing something.

 

At the bottom of the seat there are 2 hook like setup and on the top there are 3. The top just lift off the bottom ones are the key.

Picture where the 2 outside passengers would sit. In the middle of their seat postion or spine would be about b..t crack high is the hook. Push back in this area and then lift. On my truck the driver side was easy but the passenger side I had to push with all I had and have a friend pull up un the seat.

Don't forget to push all the way back first or you will never get it off. I can remove my seat and send you pics if you need.
