A slightly more elaborate method for toe is to use string lines -

Get two pieces of wood of angle iron that are wider than the car and clamp across the front and back. Find the centre of the car then mark two equal spacings wider than the car on the 'jig' then put a notch into your jig - repeat at the other end of the car. Now tie a piece of string around the jig at one end making sure it sits in your notch. pull the string to the front of the car, rest it over the 'jig' sitting in the notch and tie a big weight on the end. Repeat on both sides of the car. You can now measure the distance from the string line to the wheel rims, set the steering straight then by measuring offsets from the string line and a bit of trig you can determine your toe settings. Advantage of this method is that you can do all the wheels with the same setup and also if you clamp the 'jigs' to the car you can do any remedial work with everything setup and just remove the string for access.

We used to use this method on one of our race cars and actually put dowels in the chassis so the bars could just be dropped on and held with a quick clamp.
