1968 442 Air Cleaner Decal
 

Is there any rhyme or reason to which air cleaner decal a car got? I have a Rocket 400 decal, but am also seeing 442 decals out there. Want to get my new project back to factory original shape! Thanks!

While I'm at it, this may be a bigger issue. I may have the wrong air cleaner. It appears to be the right color, and it fits on the carb, but the hoses don't seem to line up and there doesn't appear to be an inlet for the pcv. I've seen it oriented a couple ways, neither of which seems to get me where I need to be. Any ideas?
