Personal opinion:
First, it belongs to you and I support your right to do as you please with it.
However, given the rarity of 2 door and 4 door sedans, and the fact that all Eagles are becoming more scarce all the time, I cringe when I see one being drastically modified except to save it from the crusher.
You apparently have the skills to pull this off. All too often those without the skills begin a project and end up destroying another Eagle.
