Hey Larry !! You need to reshape the quarter window if you don’t already know that. It’s longer and more rounded than a Chevelle window. Here’s a couple of pictures of my 69 I’ve been pushing aside for way to long. It started as a Perry’s 68 . I corrected the nose shape made a 69 front bumper and grille and fixed the rear windshield shape. It’s way different from a Chevelle also. I corrected the front and rear wheel openings as well.
