I did something similar but just used a sheet of galvanized steel. I’m sure your final product will be prettier. I mounted one on one side for the work light switch and another on the other side for a usb charger.I'm working on making a custom aluminum plate to house my rear working light switch. This is it so far, too cold to paint it today. But, I will paint it orange and post pics when it's all complete.

Thanks! I like trying to make stuff look as factory as possible.Looks almost factory! I chanced it and drilled a hole in my dash for my switch lol
