These preformed versions of the rear 1/4 window seals were not available for awhile, so we also offer bulk seal, see P55/15 and P55/15/A.  This is for thepreformed  right hand side of the car.  Yes this seal goes around the quarter light opening and even has the fuzzy stuff. Works for all Marks, but needs slight modification for nonopening 1/4 lites, instructions included.
