1967 - 1968 Mercury Cougar coupe clear glass for the passenger side rear seating area, it will not have the faint green tint like the SUN-X factory tinted glass. Very good used door glass with no deep scratches (multiple faint scratches and water spots often will be present). Not perfect but the best you could expect to find from a 50 year old plus parts car and will of course be a better fit than repro.
*NOTE* Air conditioning cars were supposed to have SUN-X tinted glass. Look for the SUN-X logo in the bottom rear corner.
