Allstate: Just as a little point of clarification, the sill plate is small, just reaching from the flat floor under the trimmed floor covering up and over the raised feature on the floor at the inside of the closed door, but there's a second part, a metal reinforced rubber mat that reaches from the al sill plate under the door like you are describing. I am at work and don't have access to my parts book, but I am pretty sure there's published illustrations. Chevs of the 40s has these parts available new, and they are pretty good looking parts.
