When I fitted the rear fairing I noticed that the top rear section of the fairing was cut too narrow ( By the factory ) for the final hole to attach to the 3rd rivnut from the back of the vertical stabiliser. I have tried my hand at fiberglassing to widen the rear section of the top fairing by about 10mm to allow the final hole to be drilled. I will do one side first to ensure it works before I tackle the other side.
