Properly restore the exterior of your 1987-1993 Mustang coupe with a set of brand-new coupe quarter windows from Daniel Carpenter Reproductions! Deterioration due to UV exposure, harsh heat, wind, rain, and other elements may have caused pitting and fading on the edges of your quarter windows, which can quickly diminish the look of your Fox Body coupe. For years the easiest solution to this problem was to purchase a set of Carlite coupe quarter windows. Over time, Carlite stopped manufacturing these windows, which have since become tough to find, costing thousands of dollars for a NOS set. Another option has been to have your factory windows refinished, but this process can take months, and the results could be less than satisfactory. Daniel Carpenter Reproductions has set out to resolve this issue by engineering a factory-quality coupe quarter window set at an economical price! DCR redid the mounting style so that they are now attached using a standard window sealer using the studs merely hand tight to locate the window final torques specs are 2-3 inch-pounds. Thus getting a stronger bond to the chassis versus the older butyl rubber and risking the studs breaking from overtightening.

Coupe Quarter Window Install Process
- So, depending on everyone's preference, you may take the opportunity to have the new quarter windows tinted before you install them. Use a clean microfiber towel and prep spray to remove any residues from the outside and inside of the car.
- Place one of the quarter windows face down onto a microfiber towel on a workbench.
- Use the provided sandpaper and scuff the back side of the quarter window where the silicone sealant will be applied.
- Scuff the areas around each stud.
- Blow away the debris with compressed air and wipe the scuffed areas with a microfiber towel and prep spray.
- Install the tube of silicone into a caulking gun. Cut the tip to accommodate a 3/8-the bead of silicone.
- Starting at the upper corner, begin applying a 3/8 bead of silicone. Work your way around the perimeter of the glass.
- Now, you can apply silicone around each stud.
- Position the quarter glass and ensure that the small tab is positioned underneath the roof rail molding and that the studs pass through their respective holes in the car's body.
- Lightly apply pressure to the glass and apply painter's tape across the glass and the car's body.
- From the inside of the car, apply additional silicone to the inside perimeter of the window. It may help to smooth the area with your finger.
- From inside the car, install (7) nuts with mastic sealer to each stud. Run each down in a circular pattern until they are finger-tight, approximately 2-3 in-lbs. It's important not to overtighten these nuts as they can pull out from the quarter window!! Once you feel the slightest bit of resistance, STOP turning!!
- Once the glass is installed, repeat these same steps for the other side. Allow 24 hours or longer, depending on the ambient conditions, for the silicone to fully cure.
- Once the silicone has cured, you can perform a leak test on both sides. We used a moderate water stream to simulate a hard rain storm or a light-duty pressure washer closely.
Slowly move the stream of water around the glass for a minute or two. Poke your head inside the car and inspect for any water that may be present. If there is, dry the surrounding area, and apply additional silicone as needed.
- Before reinstalling your interior rear quarter panel and other interior trim pieces, it would be a good time to clean them or prep and paint them thoroughly.
- You'll now want to reinstall the interior trim pieces. After that, you're good to go!
