Last, but not least, I’ll show three pics of adding strings to the rear wheels/tires. I just did a quick mock up and took the pics since it was 100o’s out there today.

Tape the string, on the rear tires, in the same manner as the fronts. You’ll need four jugs instead of two.

Leave the front jugs in place once you’ve got the front tires aligned. Bring the rear strings up to their jugs, which should be a little more forward than the front tire jugs. Stretch the string tight and adjust as per the front procedure.
