If your ignition switch is like my 94, there is a rod from the tumbler to the switch on the lower end of the steering colum. Down near the brake pedel. That's what I had to replace for a simular problem on mine. And have you looked at the price of the turn/cruise arm? Mine broke out the bottom a while back.
