Need help tracking down some parts
I'm working on a 650b Schwinn World Tourist conversion/transformation for my fiancee. This bike is the women's version step-through frame and came with four black plastic cable clamps which attach to the downtube and chainstay used to route the rear derailleur cable.
I no longer have a rear derailleur on this bike, but I do have a Sturmey-Archer hub laced to the rear wheel, and while the black plastic clamps work fine they don't really match the aesthetics of the rest of the bike. I have seen pictures via Google search that show some of these bikes with chrome clamps which are exactly what I want.
Exhibit C [note chrome cable clamps]
I've searched and searched but can't seem to find any of the chrome ones for sale anywhere. I am aware of the "dia-compe cable guides" but those would only work for the downtube and not the chainstay as the size of the chainstay tapers smaller from front to back, and thus the clamps are different diameters. The next best idea I have is to paint the plastic ones I have chrome or silver.
Any help is much appreciated!
Here is the bike right now in partially assembled state:
