My old one has worn out, and I do not think anybody makes them anymore. I'd prefer NOS, but a good used one would work, too.

 

You might try Rare Parts out of California. I don't know if they will hae exactly what you are looking for, but they might. They manufacture a lot of obsolete front/read end parts, including bearings/seals/etc. Pricy, but great quality, and great to work with.
