I'm sure you know, but the rear quarter panel can't be just replaced. there is no way that a shop ca possiblt pull it out and form it to look anything like what it used to. The one wreck I had with my first Z, it looked like all was needed was a new door, but there was a small crinkle in the quarter panel, so they totaled it...that part of the Z can't just be up screwed and popped off. Sorry
