On the left of the column, you have choke and light switch. On right of column you have ignition switch. You have three holes over the radio area. From left to right they are wiper, lighter, throttle. (that thar would be your "far right throttle"). Economy heater is a knob on a delete plate. Deluxe is levers on a control station in the dash.
As said, on something like this, we would like to see pictures for future reference. Even a 58-59 GMC Fleet Option had all the holes.
