Cody,
That tool from year one is for the GM style locking plate that sits on top of the turn signal switch. It has to be held down while a little wire retainer is either removed or installed. Mopars used GM tilt type columns in the Cordoba. Which is the one I put in my '70 Challenger. If you ever had to take one of those off, it's a real bear to put it back on. I found that a piece of 1/2 conduit and the Nut is enough to put it back together without that tool.
