It's not magic. It's just ECS's policy not to supply decals to the general public. This may be an agreement between ECS and GM for licensing approval.
Anyway, the tire placard is even LESS than a big deal. You can even buy the decal in various places. GM p/n 19206430. Problem is, the decal comes empty, you have to fill in your own info.
I've got a tire placard I'm working on and also the door sticker.
I'm working on some stuff now for my own cars in the event something happens to it. Even got the QR code on it which is simply the VIN number in QR code form.
Here's a work in progress sample of the door label. The barcode even scans correctly. Still got to tweak it better as I was just going off of guesses on the layout. Almost done minus the tweaks, but it's pretty close right now. And then I can laser print it on the label material and cut it out to the right size on my vinyl plotter. (part of the label obscured for obvious reasons).
