It’s touch and go as far as material/metal available on the bottom end. Total material available: 1.146. Crankshaft at that fit: .685. When you subtract that portion from 1.146, sure does not make it easy to find that thin of a fit seal; but it "might be available"? Remember the seal has to have metal holding it to when doing the calculations? The oldtime friend of mine that owned a dealership and large shop is the one who recommended to o-ring the bottom; that’s why I took the easy way in doing it. He was telling me they did several like that, and it works very soundly.
