My 05 is missing hte rack, and the bolts for the rack. I bought a givi rack, but you are supposed to use the existing 4 bolts to mount it under the passenger seat. Does anyone know what size these are? I had a M8 course thread, but it felt like it was stripping the threads. I didn't want to push it cause they are threading into aluminum. It doesn't look like fine threads. Could it be a standard bolt? If someone can pull a bolt and tell me the diameter and thread pitch I would greatly appreciate it
