For the Dementor SS are these carbon fiber roofs. In three flavors the Little G, Big G and the DUV. Mount them on the outside of the chassis and give them a little pinch on the top. If you mount then to the inside of the chassis you will need to remove 3mm of material from whatever brace or panel you choose to use.
All will require crossmembers or roof panels to complete.
