This is the trunk. To keep fumes down, I decided the fuel cell needed to be completely under the floor. The cell was mounted as low as possible, and I bought a thread-in cover with an O-Ring that goes in the trunk floor.
I didn't have the budget for an outside filler neck, so I thought this was a reasonable compromise.
At this point, I'm going to finish the floor boards and seat mounts, then do another round of primer! Then, I'll be going after the rear body sheetmetal.
