2. Remove the 1/2-inch nut holding the Mustang pivot tension spring at the bottom of the window. Remove the spring, followed by the metal washer, then plastic washer bushing.

8. Now the weatherstripping can be pulled out from the window frame.
9. To install the new weatherstripping, first place the top corner of the seal in the top corner of the window frame and pull it into the corner with your finger. This will take a bit of effort.

13. Press the angled side of the Mustang fastback weatherstrip into the frame. Use a flat head screw driver to carefully tuck the weatherstripping so it's completely seated in the frame to make a tight seal.

15. Check around all the edges of the Mustang complete vent window assembly to make sure you can see no light and there is a complete seal. Lack of a complete seal will result in a noisy window or water leakage.
16. Reinstall the large metal square washer on the bottom window pivot. The rounded edge of the washer points to the back edge of the window, followed by the plastic washer bushing, then screw in the bracket. Install the second plastic washer bushing, followed by the metal washer, then the spring, and lastly the nut. Tighten the nut to the desired tension such that the window doesn't swing too freely or with too much resistance.
17. Install the window track felt, using a flat head screw driver to press in the sides as needed and screw the top of the felt to the top corner of the frame.
