Your weatherstrip can begin to dry rot and deteriorate over time, allowing rain, wind, and other elements into your Mustang. The weatherstrip in this package is Ford's revised 2001-2004 version, which is a huge upgrade for owners of 1994-2000 convertible Mustangs. The driver and passenger side weatherstrips for the front, center, and rear side rails of the convertible roof, as well as the header piece that runs along the top of the windshield and down the windshield frame, are included in this weatherstrip package. The weatherstrip is an exact replica of the original, allowing for a seamless replacement and a perfect match every time. The interior of your Mustang is kept dry and quiet thanks to factory-style rubber!

  13. Before applying the aftermarket replacement windshield header seal you will need to thoroughly clean the header area and the seal itself. Then you will need to use an adhesion promoter before utilizing the double-sided tape to adhere the leading edge of the rubber to the front face of the weatherstrip channel. This will help ensure long-lasting adhesion.

  14. Laying the seal in the header before securing it with double-sided tape is recommended so that you can confirm the desired position. The two push pins per side are a part of one plate that locates and secures the rubber to the frame. (These are one-time use and could break if trying to remove them.) Only secure them when you are confident that you are ready for them to stay.

  15. You will slowly move down the post while using a smooth blade to force the rubber bead into its groove. At the end, you will press the push pins into the holes.

  16. Remove the two screws (if present) from the front of the forward weatherstrip in the roof rails.

  23. Adjust the door glass to fit firmly against the seals at the correct height. The door panel will need to be removed if any door glass adjustment is needed. Make note of the vertical stop adjustment locations. These are 11 mm bolts and can be moved up or down. Also, in order for the adjustments to be made the window needs to be free of the stops so roll it down a few inches.
