this is not any easy job -- - if you already have the rear window glass-- call the local autoglass installer -- they will remoce and install for less than $100-for labor and the glue kit--
they have the special tool to cut out the old glue/glass and the proper urethane window adhesive-- it has to be instlled correctly -- this is a one shot deal
CAUTION: Open the left front door glass before installing rear window to avoid pressurizing the passenger compartment. If a door is slammed before urethane bonding is cured, water leaks can result.
Allow the urethane at least 24 hours to cure before returning the vehicle to use.
To avoid stressing the replacement rear window, the urethane bonding material on the rear window fence should be smooth and consistent to the shape of the replacement glass.
WARNING: DO NOT USE SOLVENT BASED GLASS CLEANER TO CLEAN REAR WINDOW BEFORE APPLYING GLASS PREP AND PRIMER. POOR ADHESION CAN RESULT.
the urethane can be obtained at glass company or local parts store
