I think it is the original top. It was a one owner with only 17k miles on it when I bought it six years ago. It has white threads around the windows. There is a name brand on the windows but I don't know if that's who made the top or just the windows. I would not be surprised if it has shrunk some. I notice not long after I bought the vert that it was coming apart and could tell that someone tried gluing back together.
