Tornado, thanks for the excellent instructions. I noticed that the paper had worn away by the bottom set of hooks as well. The middle set already had some cloth or something wrapped around it, from the factory. Not sure why they didn't do that for all three sets.
This was the first time for me taking apart a car seat. What I had the most trouble figuring out was how to separate the front of the cover from the back. There's a sort of plastic clip thing running the entire width of the seat at the bottom holding it together. I'm not sure if that's typical in all cars or not.
