Horn contact plate/wire with tilt

You wouldn't think an "A" body would have Olds specific parts and in area like steering columns but I cant say I am aware of any other GM tilt steering wheels that use the split pin to cancel the turn signal. Never seen a horn contact setup like this and I have had a few GM's apart over the years. Im just really really lucky someone was actually selling the contact assembly on Ebay just when I needed it.
