With the newest Fox Body Mustang being 24 years old. Now, these cars are legitimate classic cars and like all classic cars, there are certain maintenance they're going to need. One of them is going to be weatherstrip. Now, in the case of the Fox Body Mustang, there's complete kits available but, the most common weatherstrip you're going to need is going to be the hatch and the doors, which we offer in a kit. Today, we're going to show you how to install it.

This weatherstripping kit will fit your 1979 through 1993 Mustang Hatchback. Includes brand new weatherstripping for both the driver and passenger door, along with the weatherstripping for the hatchback itself. Now, if you have a T top Mustang, you will have to cut these to use this kit but they still will work.

Now, this car, the passenger side has the normal rips and tears. The driver side has actually been replaced at one point in time but that does not fit very well, so we're going to take it apart and install this weatherstrip. The first thing to do is remove it but to do that, we have to move all the trim panels around it so you can properly remove it and then properly install the new weatherstrip.

We're going to start by removing the screws from our door seal plate. Then, remove the kick panel and the A-pillar. Now, the kick panels should have a Christmas tree clip installed. Many of them, including my car, it is missing but, if it does just pull the clip off and then, you can remove the kick panel.

Now, we move on to the quarter trim panel. You don't have to remove the entire panel, which would be a lot of work. You got to remove those screws from the front though, just so we can pull it back to see full weather stripping. The quarter trim panel loose, now you can remove the headliner trim. This just held in place by spring clips. So, getting a grip on it and just pull.

For the A-pillar now, what we're going to do is remove the screws again so we can push it back. You can remove it if you want to but to do that, the lower screws are going to require to take the speaker grill off, which is a little bit more work than you really have to do. You take off the middle screw, you can actually push it back enough that we'll be able to get the weather stripping in place. Okay, now we can remove our original weather strip. Just grab the seam and start pulling.

Now, we're going to begin the installation of our new weather strip. What I found the best place to start is pretty much line it up with the bolt from the seat belt and then, work forward and work your way around. What you're simply going to do is just put it over. There's a metal insert inside the weather strip. Just press it on to the pinch. Pay extra attention to make sure to go around the curves and it is tight against the corners and where it's most likely going to come off.

Now, the weather stripping does come with extra length. You will have to cut it to fit but, before you do so, you’re going to want to grab a small rubber mallet, work your way around again. Make sure it is all the way seated on your pinch weld before you cut anything off. Alright, now we know the weather strip is seated properly.

Now, we can cut it. Now, we want to make sure you get the cut pretty exact because you want it to be right up against the start of the weather strip. The more you gap you get there, the more likely you're going to get an air noise. Once the weather stripping is cut and in place, now we can reinstall all the panels that we removed.

Once everything is back installed, now you repeat the process on the other side and then, move on to the hatchback weatherstrip. The first step is we need to remove our factory weatherstrip. So, to do that we're going to start by removing this panel here and then, loosen up all the other panels to get it off. Going to be two screws up top and one down in the spare tire well. The center screws are moved, now I'm going to flip the carpet up. Then, to get the piece off there will be one more screw at the bottom and you've got to remove the screw on the side.

To properly install the weather strip, what we're going to do now is remove this panel here and loosen all the top screws all the way around so we can pull the panels back and get the weather strip seated properly when we install the new piece. Okay, with everything loose, now we can remove the factory weatherstrip.

What we're going to do now is just get some sort of a generic cleaner. It doesn't matter what you use but we're going to clean the whole edge up before we install our new weather stripping. Okay, so with it clean, now we're ready to install our new weatherstrip. What you're going to want to do is start right here in the middle, right where you took the other one off. This edge, you want it facing outward. This pinch, just put it over and then, press it down and just work your way around. Make sure it is seated, pushed all the way down. There's a metal tab in there that'll kind of hold it in place.

When you get down here it will be a little bit too long. That is actually on purpose. Make sure you got a good seal, you're just going to cut it to fit. Once it's cut and sealed, now we can actually go back and install all the screws removed from our panel. The last screw in, you can reinstall the cover for the spare tire well and the carpet and your installation is finished.

This weather stripping kit really covers two of the most common problem areas with these fox body hatch backs and that is the hatch area itself and the door weather strip. The proper weather strip will get rid of a lot of rattles and keep the air and noise out of our interior of our vehicle. As far as installation goes, the only tools you're going to need are a small Philips head screw driver and a small mallet. Figure about, maybe, two to two and a half hours for everything. Be back on the road in no time.
