The cheap cutting board trick worked like a charm, so for $8 and a handful of grease, I'm sold on that idea.

I also tried the string method for measuring toe, and it worked, but halfway into it I realized that since my rear tires are wider than my fronts, that the plane created by the string coming from the rears was inaccurate. In other words, the string coming from the rears was already at an angle since it had to come in to meet the thinner tires up front.

If I set toe-in to 1/16"-1/8", the actual toe-in would've been much more with the string being like that, so I set it at 0 for now. I set camber to -.5 and I'll check caster when I can drive it to my shop and have more room to turn the wheels. It's very tight in my garage at the moment. All in all this was MUCH easier than I thought it was going to be, thanks to all the help given here. In fact, this was probably one of the easier tasks I've done.
