Two special tools are needed: steering wheel puller and lock plate depresser. Both available at auto parts store for $20 or less.
This is how I got to mine on a 1987 Regal T type. It has a special steering wheel, but this should work for you too.
Pull steering wheel. Remove plastic cover (no tools needed). Depress lock plate with special tool. With 2 screwdrivers, or 1 screwdriver and needle nose pliers, pop the little ring out of the channel towards you. This ring was holding the lock plate down. Loosen the lock plate tool and bring lock plate out. Philips screwdriver to take hazard light switch off.
One Phillips screw holds the turn lever to the switch. Set the small metal arm and screw aside. Three Philips screws hold the turn indicator switch (plastic ring). Carefully tug the switch towards you. There should be just enough slack in the wiring that you don't need to unplug it below the steering column, but it's close.
Leave the switch dangling in front of the steering column. You're almost there! There's another screw that holds the ignition switch in. Remove that screw and the ignition switch. Replace everything.
I might have forgotten one or two things, but that is basically it.
You have to remove the steering wheel, and it requires special tools.

I believe that the switch is located in the ignition cylinder (which you can get from any auto parts store). Unfortunately you'll need a steering wheel puller and a tilt removal mechanism before you can start with that.
