You need the green switch that has the part # ending with 093.That switch fits all 69-70 Pontiacs with tilt except 70 Firebirds.When installed the plastic fittings that the wires are in will have to be twisted half a turn to fit into the new switch if changing non-tilt to a tilt.This switch is usually about $50.00 if bought new,not all venders have it but it is still availible.
