Key is stuck in igniton in 1986 corvette how to take key cylinder out and get new one back in

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
