if you really want to learn, go chop it up.... the worst that could happen would be replacing the parts after all... probably still cheaper than having this repair done by a bodyshop. If you don`t have any bodywork experience, this will be a huge job, but you will learn a thing or 2 along the way. Looking at the pics, I think I would replace the outer halfs of the wheelwells first. This will get you a good reference point where to go with the new metal. If you don`t know how to weld, practice first... a lot. too much heat will be your biggest enemy. maybe you can find the lips for the quarters in decent/ repairable shape... that would make things a lot easier, but if you have to fabricate them, start building in small pieces. With no experience I don`t think you want to try making them in one piece.
