Okay... some places to check are definately Directron.com... they have a pretty good selection of everything.... now depending on your level ov expertise with power tools it may be simple to use a dremel, but if you have a jigsaw or whatever that would probably be simpler... they also sell a nibbling tool, and all you need with that is a starter hole... cordless drill and then the nibbler takes little bites so you can make your shape whatever you want.( it's a non power hand tool) The window etching is very similar to the vinyl decals you see on imports... only thing is it is see thru.... I believe I posted a list of my favorite sites somewhere, but it's probably in the archive. www.7volts.com is a good place to start for instructions and links to good prices... so I'll let Speedo and the others take it from there... since I'm not all that experienced.
