Horn Part Info needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My horn used to work, then one day it stopped. I noted that when I changed the ignition lock cylinder and was putting the wheel back on I depressed the plunger on the canceling cam with the screwdriver and got a pretty big spark... I think that was when it stopped working.

Anyway, I wanted to get it working again so started to tear down the column, when I got to the turn signal switch I found a chard and small bit of copper where the plunger and spring are supposed to be, I yanked it out with some pliers.

Now I am trying to find the part # for that plunger and spring but am coming up short. Can anyone help.

Here are some pictures:

I believe they used to sell that part in the Help section of the auto parts stores.
