All 2007-2012 Wranglers have cutouts for the factory mirrors. When you want to remove your doors from your Jeep® and permanently mount side mirrors to your A pillar, you need a filler plate to fill the left over hole on your door. These new filler plates provide a steel plate that is custom fit to your Jeep®. Each filler plate attaches to the door using enclosed bolts and can be easily painted to match your door. These filler plates can also be used on Rugged Ridge® half doors if you choose not to put side mirrors on the door. Filler plates are a perfect add-on purchase when using the new Rugged Ridge® Quick release mirrors #11025.10 which place the mirrors directly on the A pillar.
