The curtain rod method in the second post is not bad, but you should not measure against the tires, measure against the wheels. The tires will not be in the exact same position all around. To compensate for this, I raise the wheel so it can be spun, visegrip a nail to a jackstand and put the nail to the center of the tread, then turn the tire a full turn to scribe a line, then do the same on the other front wheel. Then lower the car and roll it at least one full turn of the wheel to allow it to find it's correct camber position after being raised. Then measure between lines on the front and measure between lines on the back of the tire. Then adjust for them to be exactly equal. Radial tires use zero toe.

To make this a one person job, I took a piece of an old heavy steel tape measure and drilled the smallest hole I could make in one end. I put this in place with a thumbtack, then go to the other side and read the measurement. Do the same in the rear and equalize the measurements.

BTW, always check the wheel bearings for tightness prior to setting toe.

Good luck,
