Why change the course of history? The fact of the matter is, the cars were not perfect from the factory and they were delivered with errors, mistakes or inconsistencies. What ever you want to call them.

The restorer's intentions were to duplicate as close as humanly possible a factory issued car. This was achieved successfully because he had a nice original car that he was able to document as it was disassembled. The details or traits of this particular car were duplicated on the finished product, mistakes and all. Why? Because that's how it came and that's what Dave's mission was.
If you want a cookie cutter vision of Chrysler's design efforts, that simply is not historically correct.
