I'm not sure some of these stickers really had a "standard" location. I have noticed cars that appear to have the original "hot" stickers on other locations too.

The emissions stickers seems to often be on the left 400/AC car filler (and aleigned in different ways) and may be on the radiator shroud on others. I would like to see other responses to that. I recently moved mine from the shroud to the filler. (A long story behind that.)
