For toe on the front and back you can do it this way and if you take you time can get really close. All wheels have to be true and not damaged.
Park the car with the steering wheel centered.
Take two 2x4's and place two nails in each board the same distance apart but farther apart than the wheel track width of the car.
Support the boards on jack stands or whatever so that they are the height of the center of the wheels.

Wrap a string around all four nails so that the car is boxed like this.
Measure from the string to the center of each hub and adjust the boards so that the distance from the hub to string is the same all the way around.
It doesn't matter if the front or back wheels are not the same distance apart (track width), just that the distance to the string on both sides of the front and back wheels is the same. IE the distance from the string to the front wheels might be different than the back on some cars due to track difference.
Take your time setting this up.
When you have it you then measure from the string to the rim edge at the front and back of the wheel. That is your toe and you can adjust the wheels to set it right on most times.
If your steering wheel has never been moved you can also adjust the wheels to set them if needed.
Depending on your wheel size you can set the toe by knowing that a 1 deg angle equals ¼” over 14”.
So if your wheels are about 14" a 1/4" difference in the measurement between the front and back of the wheel = 1 deg.
Just remember for toe in, the front measurement must be slightly greater than the back measurement.
I did my Intrepid this way after replacing some parts and then took it for an alignment.
When they where done ask the guy how the tow was. Said it was right at spec and didn't need any adjustment.
You can use this to set the front or rear toe.
