Hey blu, were you able to get any pics of this?
I did, but unfortunately the air cleaner housing I thought came off my old '74 parts car actually turned out to be off of my '72 Challenger, which had an '83 318 in it and I quite honestly don't know what the air cleaner was originally on (not a '72 Challenger). Here are the pictures of what I've got...
For reference, this was the one that was on my '74 Dart Swinger with a 318. I'm not sure I have this one anymore. I'll check my parts horde but it's likely that it went wherever the 318 went. They're very similar, but as you can see the '74 has a different opening on it than the one I have. I'll take look around for the one from the '74
