273 style air cleaner base

I'll post what I have this evening......the top isn't chrome like 273's it's just a black one...like I guess was on some 361/383 and \6's...I need the bottom for it. It's actually going on my 241 Hemi on a run stand at this second, and it's running a 2-barrel carb. I have no bottom at all, but if I'm going to buy a base for it then I would rather have a one for normal 4 barrels and just use one of those plastic adapters that I have laying around for now while it has the Stromberg carb on it. Just trying to use what I have laying around and kind of leaving it Mopar since that's what I have.
You need a base the same diameter as the air filter.
