Show original supplier description
Add a touch of classic muscle car flair to your modern Mustang with the MMD ABS Rear Window Louver. Inspired by the iconic styling of the 1960s and 70s, this louver offers a unique visual upgrade for your S550 Fastback. Its one-piece, lift-off design allows for convenient removal, making routine cleaning of your rear window simple and hassle-free. It features a factory-style grained texture and a textured black finish that can be installed as-is for an aggressive look or painted to match your vehicle's exterior color scheme. Installation is straightforward and requires no drilling. The louver attaches to the exterior rear window using 3M automotive-grade bonding tape. While installation can be completed in approximately one hour with basic hand tools, it is recommended to allow at least 24 hours for the bonding tape to fully cure before driving. This MMD ABS Rear Window Louver is specifically designed to fit all 2015-2026 Ford Mustang Fastback models, including V6, EcoBoost, GT, GT350, and GT500 variants.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
