I installed a eaton posi unit 373 gears so I decided to add disc brake system of my 1955 Chevy hardtop few years back. Car has been on jack stands the whole time while I was doing other stuff to it. I just noticed a leak at the gasket. I put the bearing cover back the way it came off. It's square on three sides and one side has a low spot. Mine was down, should it have been facing up like the picture of the gasket?
