Convertible top weatherstrip is the most precisely fit part here, it splits on an exact production date, 01/10/16, not just a model year. A 2015 or early-2016 build could fall on either side of that line, so check your actual build date rather than assuming by year. Most other convertible-specific parts, trim, trunk weatherstrip, and accessories, fit the full 2015-2023 range without that complexity. Not sure which side of the 01/10/16 split your Mustang falls on? Our S550 exterior specialists can help you confirm before you order. Be sure to check out our selection of fender components and rear bumpers to further restore the exterior of your 2015-2023 Mustang! Shop all S550 exterior parts to complete your S550 Mustang project!
