Luckily its quite simple! I had to do it on my '07 a few months ago. It depends on if all 4 strips are in bad condition (front doors and suicide doors) or if you want to replace one at a time you can do that too. Here are a few links to get you started. You can search those part numbers from PureFJCruiser's website on google to find the best deal. Sometimes Amazon or Ebay will have these kinds of things. I wrapped a screwdriver in tape to pry them off without scratching the paint.
