1932 dual ratio inner wheel seal

Don't know about this particular application but I put modern seals in my 1935. Once you find the right bore size, the housing size can be altered with a spacer to fit if the housing size is not available.

Wheel seals are leaking trying to find new ones. Do you have to modify and reuse retainers or are new seals available? Really appreciate any help.  Dan
