The local windshield installer told my wife last night that he couldn't finish putting in the windshield on my 1967 MGB-GT 'cause the gasket from Moss was the wrong size (it had square corners instead of rounded, or vice versa - I got home too late to call him back). There's nothing in the Moss catalogue that indicates that different GT years had different windshields, and they only sell one type of gasket. Anyone have any experience with this problem before I call the glass folks back this morning?
