I purchased a Fastrax alignment tool, there are many similar ones. Setting the caster and camber are really not that difficult. There's lots of info on the web, and I think the Ford service manual also tells you how much change each thickness will change the setting(s). Determining the set of shims is easy for camber - do that first. Then determining the caster is done by swapping front and rear shims to keep the camber the same, but move the pivot point of the upper control arm forward or backwards. Changing the shims is pretty easy - the cleaner your suspension is the better. I loosen the upper control arm bolts, jack the car up so the wheels are hanging, that pulls the control arms out and loosens the shims, and then just reach in and remove/install shims. Set the toe last. I didn't get too crazy about this, it was easy enough that I made adjustments, drove the car a bit, remeasured and tweaked it again, until it was right on. Not a big job. My plan was to take the car to a shop and have a machine measurements done, but so far that's still a plan, lol.
