Just use some 3M strip caulk. Windshield ribbon will work, but you will need to stretch it out to get the five studs to stick through. If you have too much material in there, you could strip the studs with those tin nuts! Good luck! ---Keith
I had brought a tube of the Urethane that goes in a caulking gun but the Glass Installer (who was putting my Windshield back in) told me to use the Window-Weld instead as it's what they use. Matter a fact he gave me a box that I still have. You don't need much for the Opera Glass.
