Not trying to chase a customer from Brent, but...have you considered the free hole in the bottom of the airbox mod first? You can do this and then patch it easily if you don't like the end results. People that have done it (Bluesbass, GaryJames, Skippy) say the results are excellent. And it is quick, easy and did I mention the FREE part?
I have the freak on my Speedmaster and it works great. But, it is a lot of work to get it in, But once in, fuggetaboutit. The chain klanks on the bottom of the bracket and will eat a hole through the tool box, or just bend it up and toss the toolbox like I did. Besides, the toolboxes leak and will fill with water and can ruin tools. I figured that part out the hard way.
