I've got question for you guys thats had me wanderfing for a while. this past weekend my brother and me cracked mine while trying to remove it( its a 67') Well natually I said "shit" and wanted to cry.I'm always seeing people looking for glass on here.Heres the question, this makes me think initially that the glass is hard to get...however I had no problem finding one locally, is this just an issue were everybodys looking for original glass for some reason? just would like to know. thanks
