What are you using? What about custom base plates?

The setup that I am really after is that of the six pack style, but with the dual quad base.

I have looked at many websites, and all I really find is the Ford Cobra style, or the Eddy style, is that all there is?

Has any one made a custom base?

I have a Dart Sport with the six pack hood scoop, so lots of room to fit an air cleaner.

Any thoughts?
