Gear selector light

My 71 Dart has a rimblow wheel and column. The light has been burned out on the gear selector for as long as I've had the car. How do I replace this light? I assume it requires extensive disassembly of the steering column?
Check and see if the indicator lens has screws to hold it in place. The indicator lamp is directly behind it. It almost looks like it comes out the back of the opening.
