i never liked the 1987-1993 quarter windows because of the rubber trim that seemed to get deterioted over time from the sun .i always loved the svo sail panels for the cool sleek design . the svo sail mustangs were sold from 1984-1986 and not many were sold. they are a very rare car and with such a low run in production numbers a clean example will bring a good return in the future,in this pic i put the svo sail panel in to see what it would look like on the car i had to cut notches in the metal and drill new holes.most guys usually take the pre 1987 cars and put in the 1987-1993 quarter windows i am the exception.
