I'm going to second MPTech's misunderstanding. There should be no need to modify the glass for the Side Louver's. There are a number of ways to secure them to the inside of the body but the cut outs (assuming FFR cut the holes for you), should be darn near adequate enough to install the grills. Nothing close to what you are intending to open the holes up too.

I have detailed EdwardB's method of installing the louvers with pics/descriptions in my build thread starting at post #95. If you choose this method, just be sure to rough up the glass before laying down any HSRF.
