Fox Body Window Regulator Install

Posted 5/10/2019 by Taylor Ward


If you are having trouble installing the window regulator on your Fox Body Mustang please follow these steps to making the install as easy as possible. This is a preassembled unit so that means everything is included for the install. Also, the video is based on the vehicle being a hardtop so if you are replacing on a convertible the only difference is you will have to drill out additional rivets that retain the door support plate. Lastly when using the rivets for the door regulator, we didn’t use the ones that came with the assembly but used the rivet kit that we sell separately as part# LRS-63232-HDW because they are a little better quality.

Note: We also recommend that you have above average mechanical ability for this install because of the degree of difficult. If you do not, please find a reputable mechanic shop to perform this install for you.

1. With Fox body’s depending on the year model, there is a minor difference in the regulator. So, you will need to measure the distance between the frontward rivet mounting locations and the small support tab. 1 regulator will have a distance of 2” and the other 2 7/16”. This will be the only difference in the regulator assembly.

2. We also recommend to remove the door panel and measure the center to center distance between the frontward rivets. This will provide the information you need for your exact year model.

3. It is also a good idea to replace the window guide bushings and run channel. These wear out over time and will be easy to access during this install.

4. Now starting with the removal of the door panel, which is very simple on fox body’s, you will now roll back the moisture barrier, if it is still there, to expose the window motor.

5. If your door is equipped with a door speaker, you will need to loosen the retaining hardware and disconnect the electrical connection and set aside.

8. Reconnect the window switch and lower the door glass. Ensure that the glass doesn’t bottom out on the rubber bumper stop. If it does bottom out then it needs to be brought up a small amount.

14. Carefully drill out all 4 of the rivets with a 3/16 drill bit and there will be a small metal tab at the front of the regulator. This will need to be removed from the door frame.

15. Now you can bring the regulator toward the rear of the door so the arm roller can be removed from the guide then you can remove the existing window regulator from the door. Use this time to vacuum any debris in the door frame.

16. Bring the door glass down so that you can clean the arm roller guide by wiping away old grease. Also, if you are replacing the old guide bushings, we recommend cleaning the old grease for this as well.

17. Once the cleaning is done, pop in the new guide bushings and apply fresh grease to the arm roller guide and inside of the bushings.

22. Before you install the 4 rivets, make sure the run channel bracket isn’t pinched or in a bind with the new regulator.

23. Align the mounting holes and the regulator bracket with the holes in the door frame and install the new rivets.

26. Carefully pry open the door frame and reposition the guide rod and ensure that it passes through both guide bushings and both studs pass through their respective locations in the door frame. Reinstall both nuts and try to realign the washers on these nuts with the existing door frame marks.
