If you decide to build a Milner Coupe, there is a company here in La. that makes a chopped 5 window body and the bobbed rear fenders. Heres a link:

There is another place in the northeast that repops the bodies, rear bumper and most of the chassis hardware. I'm at work, and I can't remember the name of the other company, but I think I have it on my computer at home.
I aggree about correcting some of the original's flaws. It was a movie car and more about "the look" than real driveability. A little chassis tweaking would go a long way without killing the feel of the original.
Hope you do it!
