Am I nuts? 1940 Plymouth Commercial Car (Truck)

Making slow but steady progress on the truck, although it is in the stage that takes quite a bit of time - cutting and pasting and fabrication. Here are a few pictures of the new bear claw door latches I bought that Ross installed. The latches don't leave a lot of room for a key, so we are eliminating the exterior key which was just on the passenger door anyway (I don't know why they did that on the 30's and 40's cars).
