The first could be reproduced by a good print house, the second is a federal certification and only a handful of shops can reproduce them. There is a thread here somewhere discussing a company that can make them.
That said, at least in Texas, neither are needed for getting a title nor for registration. My overlander was missing the certification sticker when the Sheriff Deputy checked the VIN to get a title. As always, YMMV.
I had no idea about the seconf, (smaller sticker). I will try and search for that thread. I do not need to re-title the vehicle.
I want to replace the large one under the hood since its getting old.
Appreciate the responce Sir - make it a great day.
