mudracer, to explain patrick's last post, the FFR bodies have always been known to have a "perky butt" - i.e. the back end is lifted in comparison to the original. The trunk lid has a sharp angle to it. Also look where the exhaust exits in comparison to the side vents. Many differences. Not bad, just different. until we really see the new Mark IV FFR body, we won't know how it compares.
The SPF has a slightly raised butt. The ERA, to me, looks the most original of the fiberglass bodies.
