My .02 worth: Get a simple CAD program. measure out the dimensions of your existing panel. In the CAD program you can draw up all of the different instruments that you like. Print it to full scall (8 1/2 x 11 paper can be used and taped together as long a a scale is printed on it). Nice this is that you can experiment with several different layouts until you are happy with one. Spray glue the template onto your new panel and punch away. I have used this technique for several panels, and it has always work AWSOME -- allowing insturments to be placed extremely close together.
Hope this helps
