Gary;

The plunger has a shorter chaincase than does the swingarm as the gearbox is bolted right to the back of the engine. You should be able to dress out any imperfections on the cover using a large piece of plate glass and a sheet of fine emery paper. With modern gasket material to make a gasket you should be able to make it oil tight. Do you know where the oil is coming from? The cover seam? Could it be from the where the mainshaft enters the chaincase area behind the clutch? Is there a breather pipe?

Where, exactly, is the location of the leak? Are you certain it's at a screw hole?
Gordo's correct re resurfacing the cover. A warped inner cover or a crack at that screw hole can also create the problem. Multiple gaskets will not avail you not; a gasket is only intended to make up for manufacturing tolerance spread.
The root of the problem is right there in front of you. Look closely and you'll find it.
