The Scott Drake piece may work for what you are needing? Only reason I have knowledge of this is our '67 S-Code. My grandpa ditched the factory air cleaner the 2nd day he owned the car. Searched for a long time to find the replacement. The repop piece from Scott Drake doesn't have the proper profiles in it, BUT, for your situation it would probably work just fine. Still isn't cheap though. I think we paid $500 or more for the correct chrome one for the Mustang. Boss 302 guys are all over those things.
