Natalie,
Sounds like you grew up with a great mix of performance Fords from the 60's and 70's … and you certainly have the Cobra bug. Along with the fun of a Cobra … you will meet a lot of great folks along the way, and I have no doubt that your build thread will have quite a following.
You mention Wimbledon white with no stripes, should make for a very clean look. As mentioned above, think about the under car exhaust that exits before the rear wheel, as this will give you the choice of running the optional ERA rear suspension setup. That and the 5 speed, if you plan to do a lot of freeway driving.
You have a clear vision of what you want in a Cobra, which is great. Pass that onto Peter, then listen carefully to what Peter / Bob / Doug & crew at ERA recommend, as they have been building these cars for a very long time and know what works well. They will do their very best to build you the Cobra of your dreams.
