You have the right idea bending the angle Bob

Bob, here you can see the dummy frame inside at the roof joint.
This stopped all sorts of buckling as the roof and top skin were fitted together. Also shows the so called spot welds along the frame above the door.
Once I had the measurements I took the sheet of panel steel to a sheet metal ducting factory and they kindly cut, rolled the curve and then swaged the edges. Top in to go under the roof edge and bottom out to slip over the lower skin when the two halves are bolted together.
