I picked up some heavy aluminum for the guage faces and main part of the console.
I also picked up some heavy duty switches, which I felt would blend in and look like a 1960's era type panel.
For indicator lights, I picked up some micro LED lights, as indicators. Gives me a visual if the switch is on, but not too obtrusive.
I have a push button start button, but I am not sure that I like it, so cannot say if I will install it, yet.
I am trying to find some switch guards as shown in one of the pics here. I hope that I can find some, or else I will try and make some
