Question: Is it possible to get the complete dimensions on the M-6 mounting rails, including the holes drilled for attaching the rail to the cabinet. I have cabinets of an unknown brand with rails that are tapped holes I am looking to replace and these appear correct, but I need a full spec. sheet on dimensions
