Car is a 1980 911SC. Could anyone confirm that the steering wheel lock on the mechanical portion of the ignition switch is supposed to extend and retract when I turn the key? Thanks in advance for your help. The reason I ask is, I had a problem where my car would not shut off so I bought the electrical portion thinking that would fix it, no luck. I took the mechanical part and spayed it down with brake cleaner then some WD-40, it does not seem to be turning as far as it should.
