    Hey I’m Justin with AmericanMuscle.com, and I have with me MMD’s matte black quarter window louvers fitting your 99-04 V6, GT or Cobra Coupe. If you’re looking for a retro or modern styling part that’s going to set your ride apart from the others, look no further than MMD. They’ve quickly become the industry leader in producing cool and stylish appearance parts for Mustangs of all ages. At first glance you can see that these louvers are totally unlike anything else for the New Edge Mustang. It’s a typical louver design that typically you’d find on the back window, but has been scaled down perfectly to fit those quarter window openings. The louvers themselves are constructed using a durable, automotive grade ABS plastic, and then are finished off with that very slick matte black paint job, just like the louvers of the 60’s and 70’s. It is worth mentioning that for a few bucks more, you can pick these louvers up in a pre painted color matched option, just for a more custom look. Ok so I know these louvers are designed to improve your exterior appearance, but what about the interior? Well unfortunately the result isn’t quite the same. As you can see, the back features some casting marks and they’re just generally not all that nice to look at. We do offer some quarter window blackout decals available through the site here. These decals are designed to cover the business side of things, making for a clean look inside and out. One of the best parts about these louvers is that they install easily without the use of drilling or messy bondo. Ultimately if you decide to go with those quarter window blackout decals, you will need to install them first using a spray bottle filled with a soap and water mixture and the included squeegee. Once the decals are in place, go ahead and clean the quarter window using the supplied alcohol prep pads. Once the alcohol is dry go ahead and grab your 3M adhesion promoter, and wipe it down along all the edges where the 3M tape will go. This is a very important step because basically it’s going to ensure a nice secure bond between the louver itself and your quarter window. Once that’s done, go ahead and remove the protective backing on the pre installed 3M tape and adhere the louver carefully. Doing all this should only take you about 30 minutes, but if you are doing those quarter window blackout decals in addition, leave yourself closer to an hour. So if you’re one of the many Mustang owners out there who can’t seem to get enough of that retro louver styling, then you’ll definitely want to check out these quarter window louvers from MMD, available right here at AmericanMuscle.com

        Are the louvers open Are the louvers open so dirt will get behind them? If so how will you get the dirt out? Thanks Frank

        • These quarter window louvers are a solid piece with no openings. You shouldn't have any issues with dirt and they look awesome!

        Do you guys sell the adhesive separately? I accidentally stuck it on the weather strip so i had to pull it off and it came off.

        • We do not sell the adhesive separately. The adhesive is just going to be your standard auto-grade 3M tape that you can get at really any auto parts store. However if you do have problems with the adhesive, I would suggest calling American Muscle Customer service to see what they can do to help.

            OK for what they are. Overpriced IMHO

            I would pay $50 for the pair, not $99 - that's how much they look they're worth. The matte black plastic scuffs/marks easy; also stains too easily when anything oily gets on them (WD40). The quarter windows are very slightly concave and these faux louvers are not form-fitting to the glass (they are flat). As a consequence, the thin-width 3M tape is not strong enough to hold them to the glass so they don't stick at all at the corners (tend to "pop off" and separate from the glass) so there isn't a tight seal between the louvers and the glass, allowing water and moisture and crud to get between them, especially during car washes. They do look good on the car, though, and look almost stock (the matte black plastic does not match the stock dull-gloss side mirror housing).

            These would be OK if they didn't warp, and pull away from window. Also hard to paint, it crinkles .

            My quarter window was busted out due to me locking my keys in my car and I didn't want to spend 700$ to get it fixed so this was a great alternative. It looks nice and fixed an extremely expensive problem.
