Vintage Air and 440 6 pak

I apologize if this is not in the correct location. I am putting a Vintage Air AC on my 70 challenger with a 440 6 pack. My question is, will I need to modify the non-fresh air cleaner base to clear the standard Vintage compressor? I understand Bouchillon Performance has a Shorty compressor which should clear everything but I would just as soon use a complete Vintage Air kit if it will work with little or no modification to the air cleaner.
