The switch panel is easy to do. Take the stock control and pull off the knobs. Then pull the back off of it so all you're left with is the face plate. Get something to cut out the holes where the knobs went. Now you have three evenly spaced open holes with mounting tabs to play with.
Get some thin guage aluminum and cut it to fit over the face plate of the HVAC controls, or what's left of them rather, lol. Take some silicone and sandwich the two pieces together. Turn it upside down on a drill press and center a hole saw over the hole where the knob was and drill it out for what ever size you may need. Once the holes are cut, paint it which ever color you choose to paint it, then install your switches and bolt it into place using the stock hardware.
You now have a switch panel that will look clean as hell and is extremely sturdy, and you didn't have to ruin the pieces to your console to put in switches.
