I had my heart set on a 68 but I found a 67 for a good price. I know the 67 has the wing windows on the doors, are there any other major details that make a 67 more different than a 68? If this is the only major detail, I'm gonna buy it! Also, where do I look for rust? I'm not afraid of a rustbucket but I would like to know where to look. THANKS!!!!!!!!
