I noticed a small crack starting in the upper portion of my windshield of my 55 3600 this morning. It also is starting to get air bubbles between the glass panes. I can get a new tinted windshield for $200.00, but I have never replaced a windshield before, let alone a curved piece of glass. Is this something I should attempt? I have pretty good mechanical skills and been workin on cars/trucks since my old man would let me use his tools....(ok, I snuck a wrench or two when he wasn't lookin...lol). A local glass shop wanted 150.00 in labor to install this windshield. Not lookin to spend any extra ching on a windshield install right now... I have also heard other guys talk about windshield rain "weep holes"? Does this truck have them? What have fellow stovebolters ran into when attempting this? Brian
