To get a rough allignment pick a either get a stright edge or two 2x4 lay them across the front wheels so the boards are sitting long ways next to the car. The take measurments from the drivers side to the passenger side on in front of the tire one behind. Adjust you tie rods until those numbers are the same then you can go get it alligned because this just gives you a rough estimate.
