I always just put a mark in the center of the tire on the front and the back and use a tape measure. Must do work pretty good because I would do it to cars after front end work, then take them to the alignment shop and they might be 1-2 deg off. Pretty easy on a GT as you can do it by yourself.
By the way, they should toe in, not be square. Check your book. Should say 1/8". I'll go up to a 1/4".
