Quarter window on automobiles and closed carriages may be a side window in the front door or located on each side of the car just forward of the rear window of the vehicle. Only some cars have them. In some cases the fixed quarter glass may set in the corner or "C-pillar" of the vehicle.

Older vehicles frequently separated their side windows into two separate pieces. The main window resembles the ones we know today, and could be raised or lowered through a handle on the door. The second piece is triangular in shape, opened outward, and listed in manuals as a "quarter window" or "quarter glass".

In regards to the '87 model year, Ford has changed to a much cleaner-looking rear mustang quarter windows assembly for the Mustang hatchbacks and hardtops. Built from vulcanized rubber, along with the actual window glass embedded, the one-piece assembly was very hard for the mustang quarter windows, but its purpose was met being it blended the roof into the rear quarter-panel. However, with over time and many hours of hot sun baking the side windows, the exterior rubber melted, leaving the perimeter of the window pitted and discolored.

It is unfortunate that the "quarter windows" on Mustangs have begun to deteriorate, and are rather expensive to replace properly. Some owners have moved to drastic measures such as paint and patch kits, but these only work for brief periods of time.

Priced at $599.95 per pair and available for both hatchbacks and hardtops, the windows are identical to the original Ford assemblies, right down to the Mustang lettering on the glass.

Making changes to the rear mustang quarter windows is a simple R&R procedure. Reaching the nine retaining nuts for each of the mustang windows is the hardest part; basically, for the hatchback, you will need to take off all the plastic trim in the rear of the interior. However, during almost all of this process you are working with small Phillips head screws, but, you will need to have the right socket for unbolting the front seatbelt mechanism on both sides of the car.

Quarter windows, i.e. the windows found just forward of the rear window of the car, present an obstacle for the Ford Mustang enthusiast.

The Mustang quarter windows are made by an original parts manufacturer, and are an excellent and affordable option to "patch-and-paint" kits. These measures simply do not work long term.
