Is there a website that illustrates the detail differences between the '65-'69 Corvairs? I hate to say it, but they all look alike to me, except for the obvious side marker lights on the '68 and '69.
The late model (65-69) Corvairs were fairly identical from the outside. The only major exterior differences were the taillights and markers on the fenders. The '65 taillights are different from the '66 + years. Also, the Monza and Corsa trims have emblems on the front fenders behind the wheel well. I believe the '65's also had the front emblem on the hood rather than the nose. The main differences in the late models were mechanical in nature such as brakes, electrical, steering column, and the interior (all I can remember right now). The early models had more differences between years, though still not many.
