typically you don't want to crank on the strut rods to adjust the caster. This will eat up the lower control arm bushings more quickly. On shimmed control arm cars, caster is usually adjusted by shimming the control arm more at the front or back pivot point only. This will move the upper balljoint forward or rearward causing a change in caster. Once the caster is set, even shims at both pivot points will adjust camber only. Then you set the toe. Like Geezer said, anyone who can do a mustang can do one of these trucks. Front suspension setup is identical (if you're two wheel drive).
