Replace your 1983-1993 Mustang convertible top side rail weatherstrip with this 5.0 Resto package to stop leaks in their tracks. This weatherstrip extends from the back of the door to the top of the quarter window, adhering to the underside of the convertible frame's top side rail extension. This weatherstrip can deteriorate over time as it is exposed to the elements, eventually allowing wind and water to leak through. Keep the elements out of your Fox Body Mustang with this new top side rail weatherstrip.

The most commonly worn and replace weatherstrip on a Fox convertible can be found in our 5.0Resto five piece convertible weatherstrip kit. Each kit includes a header weatherstrip, two pillar post weatherstrips, and two side rail weatherstrips. All our 5.0Resto weatherstrip is premium quality replacement so you don't have to worry about deterioration or fitment issues.

And speaking of fitment, it all comes down to proper installation. We want to show you some of the basics to get these weatherstrips installed on your Fox convertible. Also, keep in mind that any time you replace a weatherstrip on your Mustang, some adjustment may be needed to compensate for the thicker, denser weatherstrip.

I've started with the header weatherstrip, being the top was already down. Take your time and make sure the metal channel is completely free of old weatherstrip and adhesive. A wipe down with rubbing alcohol is a good added measured. Using 3M weatherstrip adhesive, I applied a bead to the channel and then to the weatherstrip.

Once the adhesive becomes tacky, carefully lay the weatherstrip into place, fully engaging it into the metal channel. Take your time. You only want to do this once. I did the windshield portion of the header first, followed by the two sides. Then I moved on to the pillar post weatherstrip, following the same removal and replacement steps. Remember, cleanliness is key.

After putting the top back up, the side rail weatherstrips were the last on the list. Follow the same removal and install procedures that you have been. With the 5.0Resto five piece convertible top weatherstrip kit installed, we completely ridded ourselves of wind noise and water leaks. Anytime you put on a new weatherstrip, you do want to plan on having some sort of adjustment as your door window glass and quarter window glass may need to be tweaked to get the proper closed fit. You can pick up these weatherstrips along with all the other weatherstrip needed for your Fox Mustang at latemodelrestoration.com.
