Great job.. That's exactly the way to do it. You can always just get a new blank and start over if needed. Ron
This is what I did to save money for my switches. After I installed my roof lights I removed the blanks and hollowed them out with a dremel uing a saw tooth disk. It worked out good.Of course I would have liked using the real switches from TRD mabey later on,thats why I didnt want to make new holes in the dash.
