1965-1966 Mustang Door Glass Run Weatherstrip Pair

This Pair of Door Glass Run Weatherstrip will fit all 1965-1966 Mustangs.

The original pair of door glass run weatherstripping is made from felt, and is likely worn out by this point in the life of your 1965-1966 Mustang. Replace it with this new original-style weatherstripping, which runs along the back edge of the vent window and extends down into the door. The pair fits driver and passenger sides.

Install Difficulty:

• 
• Moderate Project

1. To start the installation process of your new Mustang Door Glass Run Weatherstrip Pair, remove the window from the door and use a rubber mallet to remove the glass run.

2. Remove the nut, washers and Mustang vent window pivot tension spring. Set everything aside, keeping it all in order so you know how to reinstall.

3. Remove the two screws retaining the pivot bracket. Then, remove the remaining washers and take note of the orientation of the metal one.

4. Drill out the rivet retaining the top seal; a 1/8 inch drill bit works.

5. From the open position, force the glass down, in the direction indicated, into the rubber weatherstrip, and dislodge the upper pivot point.

6. Now, lift the lower pivot shaft out of the Mustang weatherstrip.

7. Remove the division bar weatherstrip by drilling out the four rivets. This time use a 3/32 inch bit.

8. Remove the vent window weatherstrip. It might be necessary to cautiously begin this removal with a scraper.

9. After cleaning the chrome of old paint and/or rust, begin reassembly by installing the new Mustang vent division bar weatherstrip.

10. With the weatherstrip inserted in the channel, put one rivet in position from the front side of the weatherstrip.

11. One method to secure the rivets is to clamp a chisel or other suitable tool in a vise and position the rivet with the head against the chisel. Another option is the Mustang vent window rivet tool kit, which will make the job much easier.

12. Close up of the rivet…

13. Use a punch to “mushroom” the rivet (not shown in position against chisel.)

14. Now use a steel drift to flatten the rivet and secure the weatherstrip to the Mustang door glass track run. Repeat for the other three rivets. (not shown in position against chisel.)

15. The installed rivets will be covered by the door glass run, so it is only important that they are tight.

16. Loosen or remove the screw at the top of the division bar. The bottom is attached with rivets that are not included. It is NOT necessary to remove the rivets.

17. With the screw removed, you can gain extra room to begin installing the vent window weatherstrip.

18. Be sure to insert the rubber tab on the division bar weatherstrip into the Mustang vent window weatherstrip.

19. The rubber tab on the division bar weatherstrip needs to be properly inserted into the vent window weatherstrip.

20. Continue inserting the vent window weatherstrip into the channel of the vent window assembly. A lubricant of soapy water may be helpful.

21. There is another rubber tab on the bottom of the division bar weatherstrip that must also be properly inserted into the vent window weatherstrip.

22. Use your fingers to make sure the weatherstrip is fully seated.

23. Now, reinstall the screw at the top of the division bar.

24. Reinstall the glass lower pivot shaft into the new Mustang weatherstrip.

25. Apply force in the same direction as before and insert the upper pivot back into the Mustang vent window frame.

26. The Mustang vent window glass is now in place with the new weatherstripping.

27. Reinstall the washers in the correct order.

28. Now, install the bracket.

29. Then, install the remaining washers and the spring. Tighten the nut so the glass moves freely, but is not loose.

30. Begin installing the new Mustang vent window glass frame by putting it in place in the vent window frame.

31. Then, tap the glass run home with a rubber mallet.

32. Don’t forget to transfer the special bolt from the old glass run.

33. The Mustang top vent window bar seals finish the end of the glass run.

34. Use the method previously described to install the rivet. This time, I used a brass drift to reduce marring on the rivet head, since it is visible when the door is open.

35. The installed rivet is below. The installation of your Mustang Door Glass Run Weatherstrip Pair is done.
