Volvo Convertible Rear Glass Fell Out!

My 2002 Volvo C70 convertible has has the glass come out on the back of the convertible top. The heat in South Florida has melted the glue. How can I reattach it and how do I hold the glass in place while the adhesive cures? The few quotes I’ve gotten to repair are in the $500 range. Most won’t even touch it. HELP!!

Show us pictures of the top.
