Where to find decals?
 

I did a search here for sources for decals, or perhaps how to make them, but really didn’t find anything. It seemed this would be a common topic, but maybe I don’t have the correct search term.
Anyway … was seeing if there would be a source for Shimano decals like this …

I have been interested in a set of crank replacement decals I found on eBay for some Ultegra's. I'm still a little skeptical of their quality because I can see the sticker line in the image but that's also because the camera is 6" away. Standing above a crank is a much different perspective. With 39 sold, they seem like a potentially good solution.
Clearly these won't work on your exact crank but a quick eBay search may net you something similar.

Of course, in order to slap a new set of decals on, you'd first need to debadge your current cranks either chemically or physically.

Any local sign shop that makes logos and decals for cars and commercial vehicles should be able to print up this stuff on thin clear stock.

I don't mind the line. I can see the decal line on my '92 Record rd if my eyes are a couple feet from the unit, but they seldom get that close after it's mounted.

That looks like a very good option. I see they have a large number of different logo options, including one that should work.
They come from Poland, so shipping is about as much as the set, but still looks competitive.
As an alternate, I thought Etsy might have something, but all I found were much larger logos.
