The brake pedal is for sure a strange touch. It does look like a late 50's early 60's Chrysler pedal. Someone must have liked to use their right foot. They drilled two holes through the pad and pedal and bolted it, different.
Now Big Daddy about that old cat, she is a car cat. She has to check out every vehicle that shows up, and if a window is down she will jump in. She went for a ride with a buddy of mine one day. He drove off and I hear this screech, look up and he was turning around. I guess she scared him pretty good when he realized she was in the truck with him.
