Used Kawai Seisakusho body reinforcement parts for JF3 N-Box Removed due to interference when replacing with an aftermarket dual exhaust muffler. Front Monocoque Bar HN0870-MOF-14 Front Monocoque Bar HN0870-MOF-16 Rear Monocoque Bar HN1030-MOR-00 Cusco Power Brace Part Number: 3C6 492 FS Front Side - Consider this a bonus. I purchased it used, but I haven't used it because I didn't have the screws. Set of 4 body reinforcement parts. Everything is in the pictures. The Cusco Power Brace does not have mounting screws. The other power braces listed above were used for about 2 years. There is rust and paint peeling. Since these are used items, no claims or returns are accepted. I am not a mechanic, so I cannot answer questions about compatibility or application. Thank you for your understanding.
