I ran into that same sort of thing when I resto'd old euro cars. Some I could get - most had been NLA for decades. But if they had anything bar coded or VIN related, it was several forms and 3-6 months (if even available)....plus about $30. So I started to make my own from pics and measurements of the originals.....dead nuts down to the dot matrix font (if applicable), spacing, even the tamper shading, etc. Devils in the details. lol Did ALL the decals, including brake booster, ign coil, etc. Sold ALOT of these - didn't mean to (was just really doing them for me).
Intending on doing the same with these squares once I get to that point. Gotta collect the variances each year, what codes mean what, etc.

Before/afters. Other than the front of the battery, every decal is mine.
