Topic: Source for discontinued parts?

[psykod]

Well I ordered a set of crankcase seals for my 1977 Honda CB550F that I'm rebuilding and wouldn't you know it, the one I need the most is discontinued. 

It is part #91207-370-000, (micro-fiche section E-15 #39), which is a rather large rubber encased metal plug/seal that sits right beside the drive sprocket.  At some point in this bikes life, that plug was chewed up by the chain (as well as a bit of the case around it).  Does anyone know of a source for discontinued seals?  I've already checked several Honda sources to no avail. 

If anyone has an old one laying around, I'd be glad to take it your hands!

Waiting for an email reply from him as we speak...(or type).

Don't forget, these guys are in the United Kingdom, so the time difference will have a significant effect on your reply. If you didn't look already, you can look up parts via year. I thought I saw the part you wanted.

I see it as 91207-374-000. CMSNL.com has them for 4 Euros plus shipping - maybe DSS will be cheaper. You could try partsfish, they always seem to show stock until you order something though.
Unfortunately Honda used an unusual (here anyway) size - 34mm... 35mm x 8mm are relatively easy to find at bearing shops.
