Dear Dicky san,
After finish internal reviewed process of structure DWG 31GM-55AT-0000-5C00 at KTR site , they’re insisted that have already produced the correct part “finish D/C” (same meaning of finish matching) , so might not be able to support the replacement QTY as required.
However from this case is really difficult for us to help make the decision , then can you please get in touch with KTR’s Japanese boss (Mr.Ishimaru , E-mail : ishimaru@keihin-ktr.com ) as to help correspondence and solve the problem especially.
Really sorry for the inconvenience matter.
