rough alignment question

68 barracuda - so I replaced bad idler arm and with string measurement/estimate of toe I see wheel on idler side now has significant toe out I'd like to try to correct for now and get a full alignment at shop later. Doing this adjustment is new to me - anyone got any specifics or pics on exactly where to adjust. thnx much for any insight.
While that is an option to try and adjust out yourself, I would highly recommend paying the $79 and just having it aligned now.
