In the end, I decided to just make my own. I drew it up in Inkscape, printed, cut out, & laminated it. Then, using very thin double-sided tape of the sort used by scrapbookers


Here's a side-by-side comparison, after the fact, where I realised Mazda had used gray rather than white for the graphics - but I'm happy enough with the result. The new one is smaller to allow a border for the lamination seal.

If you want to do your own, the graphic is attached (free for personal use). Just print it to an A4 sheet and it will be the right size.
