This authentic 1979 Ford Mustang door vent window is a rare find that will complete your restoration project with genuine OEM quality and period-correct functionality. The triangular vent window, also known as a wing window, was a beloved feature of late 70s Mustangs that provided excellent ventilation control and added to the car's distinctive profile. Beyond its practical benefits of allowing fresh air circulation without the buffeting of fully open windows, this vent window assembly includes the original hardware, seals, and pivot mechanisms that ensure smooth operation just as Ford intended. Finding replacement vent windows in good condition is increasingly difficult as these classic Mustangs age, making this piece particularly valuable for serious restorers who refuse to compromise on authenticity. The crystal-clear glass and intact weatherstripping will eliminate drafts, reduce wind noise, and restore that satisfying "click" when the vent is opened or closed. Whether you're bringing a barn find back to life or maintaining a show-quality example, this 1979 Mustang vent window delivers the original equipment reliability and classic styling details that separate a proper restoration from a parts-bin substitute.
