A friend of mine helped restore a car with a repro 1930 shell. I saw it, but I did not work with it. I vaguely recall it did not have the nice radius surfaces and edges of an original shell. It was more flat and angular. I don't know how much of a bear it was to fit, but it looked OK once it was on, except for the points mentioned above. It didn't look bad, but a Model A collector would notice the difference.
