Is the package tray supposed to slide under the lip of the back glass weatherstripping?

 

. Yes.

 

Yea, a tip if your having trouble is to run a string/wire up under the lip of the weatherstripping first. Then set your package tray in place and slowly pull out the string/wire. It will pull the weatherstripping up and over the edge of the package tray as you pull from one side to the other.

 

I always put the tray in after the glass.
