Just wanted to say that if your toggle lever is broken , I have never seen or at least don't remember seeing that part available . The link deuce lover sent you has good pics that show the inner workings of the toggle and the pin on back side that actually moves the switch in the box that is mounted on the back side of column. Replacement is doable if you can find one. I think purchasing the one he shared might be your best bet . I have seen various years of the very part you probably need but the 39 seems harder to find . You can do a hack job as far as the switch goes with some over the counter modern gismo but if your are like me , you want it the way it was.
