The problem with many reproduction skins is that the body lines are nowhere near as sharp and crisp as the originals. If you can stay an inch or so below the original top body line with a skin. If you can't, I would go with a quality full quarter from AMD. It kind of depends on what you can afford. A lot of replacement skins are kind of wavy and the body lines are sometimes off so they don't match up with the doors etc. Staying slightly below that body line will help control warping when you weld on the new panel.
