Question about TE fight stick

i have a TE fight stick for the PS3. i am planning to mod it with custom artwork under a plexiglass. i was just wondering if anybody knew what the dimensions of the plexi glass are? i am going to go to a company and ask them to cut the button holes in the plexiglass for me but i dont know what the dimensions of the sheet should be. i know it should be 1/16" thick (or is it 1/32") and i want to know the dimensions so that it will fit with the red rim.
