I know of where you might get a NOS replacement. Private Message me and I'll tell you where. I had posted it here earlier, but I updated the reply because somebody else might snatch it away before you responded... but I might also consider replacing the rubber only. Scott Fuller was looking into the correct rivets back a few months (January?) and replacement tire sidewall rubber is all you would need. This is assuming the rest of the hanger is good. Just an idea, but even if you replace it, I would hang onto the original one.
