I decided to make a template for the Fiberfrax and the Titanium sheet I plan to use. First I removed all the parts I had fitted. Then I used thick paper to trace out the shape of the FW. I also decided to move the fuel line stiffener from the hot side to the inside of the cabin. I custom made it so that it can be riveted to the FW angles hence it will probably be stronger than the original Van's design.
