Jdog,
I don't get it. And doing so would mean your car would not be an all original Shelby, right ??? or maybe I'm missing something.
Personally, in contrast I think you'd be better off to sell your car as a complete, original, Shelby CSX400o, and go buy a new Kirkham if you really want aluminum. Even more so, I like your car the way it is. Good Luck on this one.
