These are replacement door panels, not reproductions of the originals. They are made from molded heat resistant plastic then painted in the available colors. The paint used is mixed with an ultraviolet inhibitor to prevent damage by the sun. Door Panels are sold in sets of two and have attached window weatherstrip. Reuse your existing armrest or purchase new ones (available separately) and install them on your new door panels. Original molding and trim may not be reused. Installation hardware and instructions are included.
