Assuming you have all parts including the bracing and rubber bumper on the swing itself, installation goes something like this.
Remove right hand bumper guard and bumper end cap. Line up the bolts on the bottom part of the carrier. You'll use the top hole (on the face of the bumper) and the bottom hole (underneath bumper) to install the carrier. If you have the reinforcing piece that goes inside the bumper you just line it all ( you may have to drill some holes) up and bolt it in.
As I remember I had to alter the end cap a bit to make it look clean, a little cutting with a Dremel worked well.
The striker plate bolts to the space where your license plate goes. So, you have to remove the interior panel of the lift gate disconnect the license plate light. I don't remember all the different sizes of bolts. Make sure that the carrier and the striker line up before you commit to drilling any holes. On my 90 the lift gate skin is fiberglass so drilling was easy but you'll want some large fender washers to strengthen it up. I also put some silicone under and around the striker to keep water out.
There are also some different ways to relocate your license plate put I just put mine ON the carrier in the lower right corner, still works good.
