    I like the looks of that top plate and gasket…with your keen lathe skills can’t you make a plate that would fit inside the lower crank case and fabricate a gasket to seal the plate to the crank case…looks like the last photo shows a plate with a shallow lip that could fit into the bottom of the crank case. That plate/gasket/seal and spring would stay stationary  and the driveshaft would spin inside the carbon seal/oring. That’s what my peabrain sees anyhoo…lol.
