In case it helps, I now run the gearbox in my Ruby at 3/4" (19mm) below the top of the filler hole, as measured by a tyre tread gauge, which seems to prevent or significantly reduce oil getting onto the clutch, which has led in the past to clutch slip in top gear. And the rear axle at about 5/8" (16mm) below the bottom of the side filler hole, which seems to stop oil making its way along to the brakes on my car.
