Fox Body Quarter Window Install

Note for these steps in relation to the video it is for the passenger side, but the same steps are involved for the driver side as well. Before the install if you are wanting to tint the quarter windows now would be the time, if not we will start the steps for replacing it!

1. First you will need to remove the rear seat bottom by pushing in and up on each side of the seat


2. To remove the seat back simply lift up and out


3. To start the removal of the quarter panel you will need to remove all phillips head retaining screws


4. Use a plastic pry tool to dislodge the seat belt slot bezel


5. Carefully remove the upper seat belt trim


6. Loosen and remove the upper t50 torx bolt. Note: that lower bolt doesn’t have to be removed but we did in the video to give us a little more room.


7. Remove the rear scuff plate screw and pull out the edge of the interior rear quarter panel from underneath the scuff plate


8. Dislodge the rear and front clips that retain the metal interior trim piece to the roof of the car. Note: Be careful because this piece is known to bend easily.


9. Now the hidden phillips head screw can be removed from behind the removed trim piece.


10. To expose and remove the second phillips screw you will need to dislodge the rear metal trim


11. Pass the seat belt through the opening in the interior rear quarter panel and remove inner quarter from the car


12. Dislodge the 2 large push pins that is securing the jute padding to the c pillar


13. Remove the (7) 3/8” quarter glass retaining nuts


14. To safety remove the existing quarter window you will need to separate the old butyl. This can be done with a plastic pry tool. Work your way around the quarter glass with the pry tool


15. Now you can carefully remove the glass from the car by bringing it towards you first then pulling towards the rear of the car to separate the tab underneath the roof rail molding


16. Now you will need to clean and prep the quarter area by removing the old pieces of large sealer with a plastic scraper


17. Once the bulk is gone you can use a microfiber towel and a waterless wash solution to remove dirt and debris


18. Next use a new microfiber towel and a paint safe adhesive remover to remove any leftover butyl


19. Use another microfiber towel and isopropyl alcohol to remove any final residue from the inside and outside of the car as well as the inside of the new quarter glass window where the butyl will lay


20. Starting at the bottom corner of the quarter glass, begin laying the butyl along the small edge just to the outside of the studs


21. Apply a little pressure to the butyl with a piece of the transfer paper and work your way around the window.


22. Once you have worked your way back to the starting point you can tear off the remaining butyl and butt it up against the other end


23. Wipe the surface around the outer studs with alcohol


24. Tear off 3” of sealer and roll it into a donut-like shape and position it around the 3 studs and apply pressure


25. When putting the new quarter window back on you will first need to make sure that the small tab is positioned underneath the roof rail molding then lightly apply pressure around the molding to seat the butyl


26. From inside the car install the (7) nuts with mastic sealer to each stud and run each of them down in a circular pattern


27. DO NOT overtighten! Just get a few turns past finger tight


28. Once the glass is installed and the outer molding is making contact with the body of the car, we highly recommend doing a leak test for at least 1 minute


29. We also recommend before installing your rear interior quarter panel and other trim pieces, now would be a good time to prep/paint or thoroughly clean them


30. Reinstall the jute padding and push pins


31. Reposition the rear interior quarter panel and pass the seat belt through the slot


32. Reinstall and retighten the phillips screws that hold the inner quarter panel as well as the scuff plate


33. Reposition the metal trim pieces and fully seat the clips


34. Position the upper seat belt bolt attaching point into place and fully tighten the T50 torx bolt and reinstall the cover


35. Make sure the seat belt isn’t twisted and install the lower bolt


36. Reinstall the seat belt slot bezel


37. Reinstall the seat back and bottom
