Air cleaner with RPM air gap

I have just over 3 1/2"s from the throttle body to the hood, and a bit less as the hood has contours. I put this set-up on, but I still need to cut down my Big Gulp throttle body to Airgap adapter to make it another 1/2" lower or have a custom one made out of phenolic by Jomar Performance.
