I've used the string method. Tie a long string to an outside spoke on the rear wheel just below the running board and attach the other end to a jack stand at the same height that you put a couple feet in front of the front tire with the string stretched tight. Move the jack stand so that the string just touches either the outside front or back outside sidewall of the front tire, and then move the steering wheel so that both the front and the back sidewall of the tire are just touching the string. What you've done here is gotten one front wheel pointing straight ahead. Then attach a string to the rear wheel on the other side, stretched out taught like the first string a couple feet in front of the other side's front tire. Move the jack stand until the string just touches the rear outside sidewall of the front tire. There should be a 1/16" gap between the string and the front of the tire if you're toe in is correct..
