The emissions decal above the passenger headlight was never available for public sale. The vacuum line decal above the driver headlight had limited availability for some models and may be NLA, depending on which specific decal you need. The coolant decal has been NLA for several years, I have a few available that I'm willing to sell but they won't be particularly cheap.I am pretty sure it was Mercedes Benz of South Atlanta (mbpartsworld.com), but I would need to dig through my old emails to be sure. There are two emissions stickers and an air conditioning sicker that I am more concerned with. There is also one abut proper coolant, but that one is of lowest concern.
Looks like the R-12 red decal may be NLA, while the R-134a green decal might still be available?
