Who's running an Eddy 1405 with stock 273 air cleaner??

So dad got his carb the other day, an Eddy 1405 and the base of his factory 273 4bbl air breather doesnt fit, the diameter of the cleaner base is too small?? Any fix for this?? I chkd Edelbrock website and didnt see the same style base, or an adapter that would work....

Thanks
