Package tray installation

unless you have a rear window defogger, the package tray is held in place and properly located by two buttons with spring clips on the back that attach the package tray to the metal shelf it sits on. They just push through from the top. I have never seen insulation under the package tray from the factory but you can buy a precut piece of jute insulation to go there. I'm trying to quiet down things in my current project and put a piece of Dyna Pad under the package tray.

I'll try to get you a pic of the buttons and a pic of them in place in a car tomorrow.
