write up for seats? theres not one cause its to easy for words.
move the front seats up and forward, then un clip the wires under the seats, then unbolts them, pull the seat back, back. then lift the rear, and while lifting it lift the front and pull back some. you will also need to unbolt the seat belt from the side area. the front mounts are like a slide in and when the seat drops the hooks hold it tight.
back seat, about 1/3 in from the outside edge, put your fingers at the base of the seat cushion and lift it up, it will pop, some for the other side, then slide it forward and take it out. the back part, has 2 10 mm bolts holding it down, and your seat belts maybe bolted via the seats other two hoops.
my rear seats had nothing holding the top of the back part that i recall, but the newer seats get screwed in. you also need to cut some padding away to fit the nubs where they screw in to the sheet metal. i have not screwed the top in yet and it stay put just fine so far. been a good year so far i guess.
