87-93 Ford Mustang Coupe Quarter Windows Passenger & Driver Side OEM Carlite LX, these quarter windows need the rubber restored but the glass on each window are in very nice shape, no major scratches or rock chips.  The driver side window has hard water spots but this is something that can be polished out.  There is a company called "Quarter Horse Motorsports" that are now polishing the glass and replacing the rubber on these quarter windows. I'm not affiliated with this company just giving the information for restoration.
