Success!!! Modifying the 8 rib belt to 7 ribs was very easy to do. Just make sure you have a new blade in your utility knife and take multiple cuts. Don't try and do it with one cut, the belt is pretty tough. The blade will follow the groove so just make about four passes with the knife cutting about 4-6 inches of length at a time. Keep the blade perpendicular with the cutting surface (I used a hobby cutting mat). When I had finished the belt fell on the floor and when I picked it up I could not tell which was the original side! Perfect!
The whole operation took about ten minutes to do and saved me $10,000. 
I have worked up a design for a custom spacer for the new pulley. I'll see if I can scrounge up a piece of 1 inch aluminum rod at work tomorrow to make it. I'll post pictures of the work as it progresses. I NEED MORE BOOST!!!!
PDF of the spacer design is a 3D PDF. You can use your mouse to rotate the spacer to see the design.
