Hobcap needed

[sciroccos at earthlink.net (Jim Ruffi)]

I lost a center cap on one of my 85 wheels, which look like this:

(thanks, Timbo!)

It's a plastic cap, part number 191 601 149B.  I would imagine they fit some
other wheels, as well.

They do seem to be available new, but I figga'd someone might have a cheap
used one.
TIA!
