Help! Dog Tracking!!

When my Dart is driven down the highway, my friend says that he can see about an inch of the drivers side front tire and it looks like the car is going down the road slightly sideways. I had him drive the car and I followed and sure enough this is so. I am wondering which side of the front spring hanger that I should adjust to get it straight. I am thinking of putting some shims on the drivers side, by loosening the front hanger spring bolts and sliding them in. Or should it be the passenger side that I should be trying. I just can't seem to picture it clearly in my mind. I tried measuring from the k member center line to the front of the spring hanger and it looks to be shorter on the drivers side. Any thoughts are greatly appreciated.

What rear is in the car? What year? Revhendo is correct, the front track is wider than the rear track if you're running the A body rear.
