After learning that the Pierson coupe used a lot of '40 Ford components (suspension, brakes, steering), I figured I'd add a little more detail and picked up one of these for parts:
In case you haven't seen one, it's a beautiful kit, extremely well done. One thing led to another and I soon realized the frame and interior pan is a near drop-in to the '36 body. Here's the frame assembled and painted. The only alteration is adding a battery box under the seat (the stock '36 location).
