Unless the steering column is a tilt it did not use a bulb. They used a fiber optic cable.

Here is a picture of what the cable looks like and where it connects on the back of the cluster.... (right picture borrowed from member TBONE1964... Thanks Tom) The small end of the cable just plugs into the bottom of the indicator housing.

They aren't that hard to come by as GM used them on lots of cars and trucks in the 60's & 70's. Now if you needed the ones that came in GTO's for the backup light indicators that's in the unobtainium class.
