push button ignition

When I switched to an orange box in my old RamCharger, I did this. All I did was wire a toggle in to replace the "run" position of the key and a push-button for the starter. The stock ignition switch became nothing more than a key-holder really.

By having the toggle, I was still able to have acc. power for my radio, CB, etc. You could do the same setup with a keyed switch instead of a toggle but at that point, why not just pop a hole in the dash and install a proper ignition switch that can be key-matched to your doors?
