1966 Barracuda wheel size

Hi all,

Just bought a 2 owner Barracuda 1966 and as a Mopar "newbie" I have some questions.
I know that the bolt pattern is 5x4 (or 101,6) which you prefer. I have been looking at aftermarket wheels and they are few 5x4 wheels available as you all know.

Anyhow, I have found some American Racing Outlaws wheels.
- Wheel specs: 14" - 7" wide -5x101.6 / 5x4.0 bolt pattern - 0mm offset - 4" backspace - 72.6mm center bore - 1280lb load rating.

Will that wheel fit my stock Barracuda? Or is the wheel to wide since it's 7"
Is anyone driving with 14x7 wheels? What are largest tires you can put on without modify?
What kind of Lug Nuts is needed? Do I need Hub centric ring?

Since the car is in good condition I don't want to change bolt pattern. I want to keep it as it came from the factory.

I live in Europe I need to order from US and when I place the order I want to make sure I get everything at once...

Is there anything else I need?

Thanks!
