I was trying to remove the rear seat and I got the bottom half off but I can't get the barkrest off. I spent almost an hour trying to get it out (and not break anything) The Bentley manual says that it should slide on up but it doesn't seem to work. I even got the back headrests out but was I supposed to take the plastic trim out also? Help me please!!! Yes, I got the center armrest out and two nuts on both sides.
