Thank you for viewing. This is a Kawai Works side-mount super low position seat rail for L700 Mira, Opti, and Storia. Used for about 4 months. Includes the seat rail body and seat mounting stays. You will need to prepare the bolts for securing the seat and the seatbelt receiver stay. Please understand. There is very little wear and tear, and there is no rust. I believe it can be used without any problems. When listing, I have removed the oil while cleaning. Please be sure to apply oil before use.
