Is a 2003 Ford Windstar rear window interchangeable with a 98 Windstar rear window?

The rear window of a 2003 Ford Windstar is not directly interchangeable with a 1998 Windstar rear window. While both vehicles belong to the same model line, design changes and manufacturing differences in those years typically result in variations in dimensions and mounting mechanisms. It's best to confirm compatibility through a parts catalog or by consulting with a professional.
