There's a bolter here that did a swap on a full size a few years ago Sublime was his bolter name. When I first joined up he was so talented and kept a picture trail and gave me lots of insight. He stretched his front fenders about 3 or 4 inches to accomodate his front end. Maybe his picture trail will help you in your decision. His pics below.
