I had a difficult time getting an aftermarket air cleaner to fit the top of my Rochester 1bbl carb on my 37 Chevy pu w/56 235 engine. I ended up going to Winchester Auto Parts in Soquel and getting a tailpipe adapter and cut it down to fit. Just measure the opening in the air cleaner and the top of the carb & get pipe that fits. If they don't have it in stock, they can order it and have it there in a few days.
