I don't know squat about glass. I replaced a couple of windshields in my time but that was more than 30 years ago. I need a new windshield for my '58 Chevy truck (I still have the original but it's delaminating pretty bad around the edges). My plan right now is to have a local glass guy order a new windshield and install for me. I have no doubt that I could intall it myself but I would like to do so without breaking it, so maybe I should leave it to a pro since I would like to just buy one windshield and not two or three. My questions are: 1) I got the impression from reading some threads a while back that not all windshields are created equal. Is there more than one company that manufacturers windshields for my truck? 2) If there is more than one manufacturer, what are the quality differences and what do you pro glass guys recommend and why? 3) Any other advice? Thanks guys.
