Kevin, I was referring to your last find, looked kinda like a '69Z?
There were some deuces that got restriped very early in their lives, and it is not unusual for them to receive a different color, or in my car's case a combination of '69 and '70 stripe components. I believe you when you say the car had white stripes on it when you saw it, but it may have originally come with black - or white, we need to speak with the orig. owner (Mike??)
I am not aware of a blue with black stripe car being pulled out of a junkyard recently, the last one I heard about was in AR/CT.
