I'm hoping someone can tell me where to get my transmission output seal. I can't find one online. It's from a 3 speed manual from my 49 streamliner. The inside diameter where the drive shaft goes it 1.5 inches.

You can try Gasket City in Ontario. I have bought some gaskets and seals from him for the hydramatic in my Pontiac.
