These reproduction floor pans extend the full width with vertical flanges for easy installation and fairly well represent the original stamping. They have added metal to include the side of the tunnel on rod change cars. Just trim this extra material off for pre 1973 round tunnel floors.

This was fitted up to 1990 when they put a strengthening rib through the centre of the floor to carry pipes such as fuel lines on the single point.
