Hey PK Cruiser,
All you need to do is remove the rubber weatherstrip, no tools required and no metal trimming neccessary. I have noticed also that air turbulance shakes the hood, this is because the support the strip provided is now missing and now there is a 1 inch gap where air flows freely. Bob Stockum has a easy fix for this, he used a rubber shock mount to support the hood in the middle, check out this link, lots of good info:

If you don't have the part than do what CREWZIN and earringboy have done, just cut down the weatherstrip and replace it in key locations.
