does anybody know what this air cleaner could be for? its the same diameter as all the other 70s mopar air cleaners I have, but is about 3/4 of an inch thicker. it had a snorkle on it at one time don't know if it was a short or long one. there is no nipple for the breather hose and there are two brackets on the side(see pic) it also doesn't have the indent in the front that all the other ones I've seen have. its also a four barrel. anybody?
