Okay, I've got the templates and everything, however Radio Shack does not carry the metal nibbler anymore. Being the perfectionist I am, I don't want to cut holes with a dremel. I've found a couple of the nibblers online, however shipping is almost 1.5 weeks and I'll be on vacation / back to school by then. Does anyone know of a retail store other than Radio Shack that might carry them? I've tried Home Depot, Lowes, OSH, etc...

 

look at my write-up on this, in there i show how to do it with a dremel and theres a guy that posted the template

 

A dremel actually gives you a smoother cut. I have done about 6 installs with the dremel and they all came out perfect. Take your time and mask everything, I actually draw the template on the masking tape. Measure twice, cut once.
