Ready to install windshields, any suggestions

I had a professional come to my house for my 76. We tried roping it in with no success. He left and I was frustrated, so later that evening I tried popping the gasket on the car, then laying the glass into it (working around it slowly with a plastic glass tool.) i did put some adhesive in places , but used it very sparingly. thats how I installed mine. I had never done it before and found it to be a miserable job, but I was happy to finally have it done.
