Some more random photos I found:

A couple of 69 440 Six-Barrel Roadrunners. There was a bunch of the here for the FAST racing:
The black FAST 440 Six-Barrel roadrunner in action. The white disc on the front wheel is an original advertising disc that the dealers sold. It was a bizarre contraption. It involved a wheel bearing cover with a stud coming off of it that would mount the disc on the stud. So when the wheel turned, the disc stayed stationary and showed the giant roadrunner logo. I guess it was the prehistoric predecessor of those ridiculous "bling" wheels that have the free spinning blades that keep rotating when the car stops.
