Body to lid gasket  This is a 4 piece set. A Master measures 39.75in across the front. Black and same profile as original. When on the machine the finished size is 39in L by 22.5in W. Gasket comes with one side of each piece cut at a 45. The other side will need to be cut to fit your machine.  Glues down without using metal strip. A much cleaner look than having screw heads showing. The screws cracked the rubber and the metal strip rusts and stained.
