Replacing Ignition Switch in 73 Duster

Good news: Got the snap ring of easily by turning it with channel-lock type pliers

Bad news: Can't budge the pin. I guess I don't have a "drift pin", I tried an awl and I can't seem to find my hammer so i was using an acrylic ended one or something. So maybe I just need the right tools? But it has not moved even a tiny bit in about 20 minutes of pounding.
