Sorry for the late reply. Anytime I was on the other side of town, I would not have the camera.
Sorry for the poor quality, my camera has been acting funny lately.
The first two pictures are one of the styles. They are on my '68 Chevelle, and they work from '68-'72. At least now you know where they mount. I can try and take some better pictures for you next time if you'd like.
The last picture is of another set that I have. I believe they work for a '64-'67.
