I need some help in a way to set the toe-in for my '80s model F150. It doesn't have to be set to exact 'spec', just close. I've seen pit-crews at NASCAR races do a string-line test, how does that work? Reason for all this: every alinement shop in my local area wants $60 to just turn the sleeves on each side adjusting the toe-in. That's a lot of money for an unemployed man to spend on a 20min job. Any help would be appreciated. Maybe there is a diy website for this procedure? Thanks!
