***UPDATE***
So, I've gotten in touch with a very nice gentleman at an auto-quality custom vinyl shop, and he pointed out some stuff to look at, namely, the image that I made is a raster image, meaning it's composed of tiny little pixels, and that vinyl printers will not print them. This is because vinyl printers only use VECTOUR images, because a raster image blurs when you enlarge it. A vectour image is essentially a set of mathematical proportions that tells the display how to draw the image.
In respect to this, I am now working on building a vector image of the label (easier than I thought, but it's still going to take some time).
The guy at the print shop quoted me somewhere around $10 plus shipping for one label, probably less the more I order.
If any 6.9 people want one (or two, or three) of these, I will update with a picture of what my decal looks like if/when I finish it and get it printed. Then y'all can decide if you want one, and I can customize the decal to match your engine and truck year.
7.3 people, I need good pictures of your decals to make a baseline to start from. No promises on time, but if my decal works out, I'm happy to build a 7.3 and even a 7.3 factoury turbo decal as well.
Will post back when I have something more definitive on how the decals look!
