Expert windshield guys have told me that they cannot remove and replace my 280ZX windshield without deforming the aluminum trim so that it will never look the same again. They also say that the clips that hold the trim in place always break and replacements are not available so that they cannot replace the aluminum trim. The repair shop that takes care of the car tells me that the original windshield is much higher quality than replacements, and if the 4 inch crack does not spread, I am better off keeping the original windshield. Any thoughts?
