according to my parts manual, there is only a gasket between that cover and the housing behind it. the housing behind that cover shows having shims to set the endplay clearance of the shaft. those are roller bearings, not tapered cone bearings. your picture is also looking up from the bottom as the input shaft should be on top. just in case anyone else is trying to orientate the shafts correctly to chime in.
gasket number is 7b4570,
