Actually, I have moved these pieces around in every possible direction, and I will have to cut the outter wheel housing on both the upper and lower lip to bring it in so it matches the quarter opening.
When I clamp it on the original inner wheel housing, it does not match the curve from one side to the other. If I clamp it tight on one end, then bend it in, it pushes out in the center and interferes with the quarter panel.
The quarter panel it self fits great, and the trunk drop-off seams fine.
