Stepdown 1948 brake drum seal info

[Deleted User]

Can someone post info on a replacement seal for the front brake drum inner grease seal as my old felt one is leaking. I checked the size as follows ID 1.568 OD 2.5 thickness .25 these are as close as I can measure Thanks

OEM was Standard 1680. It crosses as National 473228 or CR 16247. These seals are still current.

Thanks for the info. CR 16247 has an ID of 1.625" and my sealing surface is 1.568" is there a seal closer to the spindle specs? I understand there may of been 2 types used in 48?
