460 Muscle

I came to this forum because I figured this the place that would have the right answers and w/o any BS. I want to build a 65-66 2+2. Everything I've read up til now indicates I need a donor car. So far, all I've seen for donors are either junk or an arm and a leg. Here's the question...does anyone make a complete"from the ground up"up kit? I don't want to build something from a Miata or anything like that. I currently own a SPF Cobra. I've seen Mustang fiberglass bodies and parts and was wondering about frames, steering, front and rear ends...etc.
Thanks
