Great 'how-to'!! Perfect timing too, as I bought a 3rd seat with the intention of taking it apart and re-covering it myself in the spring.
(Hope my mom's sewing machine is up to the task!)
I have the fabric seat/backpad and they look to be a bit different in that the fabric at the top of the back pad seems to be sewn directly to the base of the headrest vinyl where they meet.
