69 SS 427 Impala steering column Horn ring/turn signal plastic piece. A friend just passed away and I'm assisting his wife in getting some things fixed. Need this piece to get the horn working. This is the plastic piece that provides power to the horn and moves the turn signal lever. Also the other piece in the picture transfers the power from the car to the horn ring.It's supposed to have a metal piece on the outside. Are these available as aftermarket?
