After you have the shock in the control arm, go ahead and line up the holes. (a pick or screw driver can help lining them up)

Once you think the hole is lined up, shove the pointed tip bolt that was taken out from the stock shock earlier.

To slide the bolt it completely, you may need to tap it with a mallet or thread a nut on it and tighten the nut to pull the bolt all the way through.
