How to "rough in" front end alignment after rebuild?
The ACCURATE way to set toe is to make yourself a scratch device, AKA a nail through a board that you can hold in one place accurately. Jack the tire up a small amount under the lower arm so you can spin it. Hold your marker device down, and scratch the tire in two places, 1/2 turn apart. "Somewhere in the middle" does not matter where, as long as the scratch device does not move. This creates "a plane" through the tire.
Now with the tires on the ground and your marks horizontal front--to rear, either use a helper with a tape to measure front and rear of the tires, or else build yourself a gauge. A simple sliding trammel gauge with a fixed nail on one end, sliding nail on the other so you can hold it to the tire marks, measure that(or mark it on the gauge) then do the opposite end of the tire and compare the difference.
Does not need to be this elaborate:
Tire scribing
This is similar to my tire scribe, which you can build. I got this one with the toe gauge. LOL---I had to cut that toe gauge way way down, as it turned out to be made for trucks and way too tall. Could not tell that from the photos in the auction!!!
