273 air cleaner base for a four barrel carb

I understand what you all are saying but the problem is I have a edelbrock 600 carb. and if I use the edelbrock air cleaner base which is flat the wing nut will hit the hood. I need the factory or a similar base which is recessed to drop the air cleaner down. I have several flat air cleaner bases which I have tried already.
Does Summit racing sell just the base for the air cleaners? I didn't see one for a 10".
