Windshield Removal '73 Swinger

My buddy works for Safelite, and they told you it would break because his company tells them to tell the customer it might so the customer won't get pissed if it does, the older gasketed glass comes out easy, the newer urethaned in glass will not, they crack coming out! I have a long blade and thats the way I plan on getting my front glass out and I will have him get me a new front glass and both front and rear gaskets when I paint my car, kinda nice having friends that can hook you up!
