Parts for the factory installed hard doors are not in the parts manual. I have found a list of all the windows and other parts for two and four door GEMs. These windows are expensive and break rather easy in cold weather. Several of these windows will ship oversize, which means an oversize price. Since GEM will not drop ship, it just cost us $200 to ship a $233 window. Try to pick up at the dealer if at all possible.
