I did look at convertible top guys, when you select Chrysler, scroll down to 1968 300 and Newport. They carry the original grain black and white, but not green. There is an option for a tinted glass or plastic rear window. I selected tinted glass rear window as glass was original for our car, although when our convertibles were ordered new with all windows tinted glass, the rear convertible window was not tinted(FYI). my configuration came to $505.
