swingarm seals

[Lonnie]

I am in the process of rebuilding a '58-'72 rear swingarm and have noticed that I have two different sets of seals, one thicker than the other. Looking in the various parts books and catalogues and even in the four different shop manuals I have, I see that the part number for the drum brake swingarm seal is different from the disc brake swingarm seal but nowhere do I see a reference for thickness. Unfortunately I trashed the parts when I prepared the part for powdercoating so I have nothing to reference.

Does anyone know which is the correct seal? FYI, I have a Drag Specialities kit.

Thanks,

I measured these three seals for thickness.

47519-58 = 0.490", this was measured trough the factory plastic packaging.

47519-72 = 0.318", this is actual. they have a parkerized ? steel outer body.

47519-83 = 0.400", through the bag again.

Hope this helps.
