The rear valance corners just didn't want to fit. As you can see, they gap on the forward edge and they don't line up with the tail panel character line either. Hopefully this series of pictures can help some future builders.





A section was cut out. The piece was rotated slightly and welded back in. The rotation created a small "pie slice" shaped gap at the forward edge.




Next the rear valance was sliced along the top to again bring the edge out
