Emissions label decal locations

[CudaMoparRay]

Trying to find the "proper" location (if any) for a 1972 Plymouth 'Cuda 340 Emissions decal that is bigger than the locations pictured.
Where should it be placed??

Anybody know where to put them
?

It's a '72 challenger engine compartment. Not sure if they are the same. Hope it helps...

Thank you @TelisSE440 this seems to be the preferred slap it on location sometimes give or take 6 inches depending on if a Monday or Friday

Just be glad its not a California car... Or you'd get the decal on the drivers side quarter window....
