On mine, there is no seam going form the 1/4 window to the rear glass. The seam runs across the top above the rear window at about the crown of the top. The drip rails on mine stop a short way down from the top of the 1/4 window, then followed by wire-on. I have pictures of my car before and during the restoration which do not show any drip rail going down to the belt molding. If they are supposed to be there, mine didn't have them. John
