Or are we stuck with the old leather ring?
Anyone happen to know a size or number so I can check if my local bearing shop has one before I pull the sprocket off?

NOS oem seals are still very good if warmed up good before installing the sprocket onto the mainshaft. I now heat them up to roughly 175 degrees before installing them. The heat seems to make them plyable again.

Ask for an nos sprocket instead of just the seal. The seal will already be installed in the nos sprocket. To answer your warming of the seal question....no....I do not warm them in oil. The nos seals, and or the nos sprockets, are coated in cosmoline, and.... to remove the vast majority of this preservative, the heat accomplishes that task and simultaniously enhances the softening process to boot.

I would not worry about the OD, find a seal that fits the boss on the end cover and make your own "seal retainer" to fit the OD to the sprocket.
