The track that is one it is for a 1967 1968 Ford Mustang.  The glass is the same for all years.  The stainless is close, and if you install a  lower track off  1965 1966, you may have to drill 2 small holes for the set screws in the track flange.  It is not visible when installed.  

I do not have a Cougar track.  

Good overall shape, original Carlite glass.  Some small scratches will be somewhere on the glass, but nothing glaring.  

This is cheaper than buying a new metal track and stainless molding.  

I have 2 available, both right side
