Congrats! the car looks like it's in pretty good shape. your situation reminds me a lot like mine. i have a '36 Plymouth coupe and i also had a '36 sedan as a donor car. this past winter has been the season for the body work, in michigan here that means you have a long time to get things done.
i was curious about the patch panels and also the rear fenders. i bought some patch panels for the same area you did, but i got them from some guy on the east coast. who is this guy Bob? are the rear fenders steel or fiberglass? reason being, i can't find steel fenders for a decent price to save my butt. anyway, good luck with your project,
