Yes, that was the link I was going to give him if he was interested plus the below pics.
Measuring between the tires as is done in that link works fine. Be sure to set the fronts so they are between 1/16" and 1/8" closer together than in the rear.
The two below pics show a more accurate and repeatable way of setting the toe-in. All it takes are two pieces of 1" square aluminum (or steel) tubing marked at points equal to the tire diameter, and a couple spring clamps to hold them to the brake rotor.
This last method takes a little more time since you have to remove the front wheels but I can get the results as accurately as I want them a little more easily this way.
