With the two sides of the cut section moved back different amounts, the scuttle top was twisted so I cut it above the car's centreline. I then adjusted the screen position to get the edge where it meets the quarterlight pointing towards what will be the front shutline.
I then moved each side of the body to get the overall screen movement 5" to the rear and the screen square to the body. The right side ended up 6" back and the left side 4" back.
