Yanmar 2000 rear axle oil seal needed

[Old Clunker]

I disassembled my YM 2000 rear axle hub and found the leaking oil seal and the race that it rides on was worn badly. The Seal is a NOK AE3045E. I cannot find one anywhere and Hoye Tractor does not list an oil seal for the axle. Has anyone had any luck cross referencing it over to another maker or at least another use. I did find that NOK makes oil seals for motorcycle forks that appear close in design. No way to know the cross over as none have specs.

Does anyone have any ideas where to find a seal? Thanks
