dust seals

[ADK]

In the process of re-packing my wheel bearings I have discovered two problems. The bearings themselves are pretty much standard size but the grease seals are not. Consequently the dust caps, which are non-existent are not a standard size either. I do not know the heritage of this trailer so I cannot go back to the manufacturer for info.
I think that NAPA can cross reference my seals (no markings on the seals.)but absolutely no luck on dust caps, any suggestions? The ID hub size mikes out to 2.0625"
Replacing the hubs is an option but only after all possibilities of finding replacement parts have been exhausted.

A 53mm dust cap might fit if the edge has enough of a taper to get it started. It is about 14 thousandths of an inch bigger than your hub opening. It is an older GM size.

Find someone with a lathe, have them open the ID of the hub to accept a slightly larger than original dust cap. I had to bore the hubs on my trailer for the same reason.

Thanks Kevin & Steve, I believe I have found a source that may have what I need and may also be useful info for others with the same issue. RedTrailer at http://www.redtrailers.com has a dust cap for 2.0625" hubs and grease seals for the same. I have not ordered yet, I am going to send an e-mail with my technical questions and see if in fact they are correct.
