Nah. I like the overall looks of the '39. Headlamps and tail lamps, etc. But, I like the features of the 40's. Like the column shift lever and the vent windows, etc. So AMT's '39/'40 kit is perfect as far as the features I want. I can build a model that has best features of both years. I'm happy with this. Besides, if I want a Standard '40, I have Revell's '40 coupe kit for that. Even then, I will be including the right taillight on that one. My models do not always need to be exact representations of the real thing. I like them close. But, I'm willing to sometimes look the other way on minor things.
Nice model above, by the way.
