Air Cleaner for Stromberg

I need a new air cleaner for the stromberg carb on my '51 buick (263) and wanted to put on one of the Olds/Cadillac repop air cleaners. The issue is that the opening for the air cleaner is much larger than the neck of the carb and also the air cleaner is held on by a nut attached to a rod that is attached to the carb. Is there an adapter that anyone knows of that will fit and make this work?

 

Have a machine shop make you one out of aluminum.Maybe the repop guy has them?
Good luck.
