The (3) holes shown above will be used to mount the lower control arm skid to the lower control arm.
With the skid lined up to each of the (3) holes, insert a carriage bolt though the bottom of the skid up through the control arm, with a washer and nylock nut on top. Leave everything loose.
With all of your bolts started, use a wrench to tighten them all down into place. Repeat this same process on the other control arm to complete your install.
