Protecting the interior of your Mustang is just as important as the looks of it. American Muscle understands that you need to have options available to you that conquer both of these concerns. With our 2005-2009 Mustang quarter window covers and decals, you will be able to provide your interior cabin with the protection it needs from the sun while also styling the exterior of your ride. All of our decals are designed to provide you with a great look, but also to last for up to eight years, which is much more than what the competition offers. Each one of our decals is designed with durability in mind and you will find that you have a large selection of colors and styles to choose from at American Muscle.
