57 chevy air cleaner

My 57 is stock. The hardest part to find and the most expensive ios the 4bbl air cleaner whether it be the oil bath or the power pack. I have been to swap meets, saw them on ebay and craigslist that go anywhere from $350 to $1,000.00. Some of them are completely rusted thru others have been restored. They are getting harder to find. I wish one of the classic car places like Danchuk, Ecklers would make a reproduction that does not cost a fortune. I have the top part with the spout but cannot find the bottom pan alone.
