On my Cabriolet the door has a metal strap about 1/2 or 3/4 inch wide that runs from the upper front to the lower rear that can be adjusted to pull the lower door in to close the gap. You have to push the lower door in and fasten the metal strap at the same time to hold the door in place . These straps are hidden behind the upholstery and I believe they are original to the door . I hope this all makes sense . Norm
