Jack one side of the front end up, unbolt the top three bolts on your strut and the bottom bolt, pull strut out, put spacer on top of the strut and bolt it on. Unbolt one of the end link bolts and loosen the bolt on the spindle to allow the lower control arm to drop a little further. Rotate strut 180 degrees and slide back into place, but bottom bolt back in and tighten it up, replace 3 nuts on top of strut and tighten up, put bolt back in the end link and tighten back up, tighten spindle bolt back up, lower truck, repeat on other side. Or buy me and my wife some tickets to Disney World, and I'll come down and do it for you.
