The breakdown is my own work. First I measured things with a yardstick, then I wrote everything down and worked out how to place it on the vinyl, then I ordered/cut the vinyl, then I figured out I was 6 inches short in a handful of places and had to adjust the diagram so people in the future don't have to have the same seams I do.
Something I forgot to mention: This is the perfect time for an antenna delete, seeing as you need to pull the antenna to wrap the roof, and you cover the hole with vinyl anyway.
