I know it's probably a long-shot, but does anyone know where I might be able to get a Shimano 105 (5500) decal, like this one?

I built my Zunow up with this version of 105 and would like some myself because the crank set has black lettering not blue.

I was told that the 5500 version of Shimano 105 was only offered for a year or two.
If true, that would make the decals extra hard to find due to a low demand.

I did a quick job of the artwork for you. You'll have to deal with scaling since I don't have an example to measure, and I sampled the colors from your photograph so I'm sure they're going to need some adjustment, but the shapes should be fairly accurate. I've recently struck out trying to find a local print shop which will even bother to call me back with a quote for any of the decal sets I need printed so hopefully people in your neck of the woods aren't as lazy as they are around here.

You'll need a vector graphics program to do any editing, but Internet Exploder (or whatever it's identifying itself as these days) should be able to view.
