In this article, we will be going over the removal and installation of the inner and outer quarter belt weatherstrips for all 1990-1993 convertible Mustangs. Often referred to as "dew wipes". The Mustang convertible inner and outer quarter window belt weatherstrips are located on the inner and outer edge of the quarter window. These help to wipe the window clean as it rolls up & down as well as provide a bit of stability to the window glass.
This 5.0 Resto Rear Quarter Belt Glass Weatherstrip is a direct replacement for the factory piece on 1990-1993 Ford Mustang convertibles. We do want to note, the inner weatherstrip design will slightly vary on the 83-89 and the 90-93 year ranges due to the interior quarter panel design. Other than the slight design changes, the installation of these parts will be the same.
You can set aside a solid afternoon to complete this task. Keep in mind, in this article you will see other parts being used. Check the links below on these items shown:
