Just putting this out there in case anyone is doing your own alignment. This tool works well but beware, the bubble level is set up for Camber. That's fine.
But when you use it to measure Caster, the scale is reversed Positive to Negative. Just be aware. If you turn the wheel outboard 20*, zero the bubble, turn inboard 20* (40 total) the scale will read Negative but that actually means Positive. This threw me for a loop last weekend until I drove over to a friends house to borrow his antique tool. It has a fixed camber bubble, and a separate caster bubble so I could see the scales were reversed.
This is not in the instructions either.
If you swing the wheels the opposite way, inboard 20* to outboard 20*, you can probably read the scale as indicated.
I like this tool b/c the magnetic base fits between two wheel studs once the nuts are removed. And it was only $15
