The rear seat backrests are held on by two metal pieces that the rear seat backrests clips into you have to push the seats up with a decent amount of force to get them out. This part of the install was the hardest I had to move both front seats forward to get enough room too put a large pry bar under the seat and push them up. You may need to wedge a block or have someone hold the first side you got out so it doesn't fall back in when removing the second side.
