I am thinking about replacing my vinyl top on my 67 Camaro. The problem is my top does not look like it is white, it looks more of an off white compared to the striped on my car. I know the stripes are not original to the car, could not get z-28 stripes on a 67 SS. But what about the top? Were there actually two different white tops available with one being a off white in 67 and 68. Or is my top from some year other than the first generation? Or,,,,,,, is it because my car is Plum that the top looks more off white than white or does age really change the color on these tops that much?
