I am renovating a 1970's home with a very compact plumbing system including this back to back wall hung toilet carrier. It looks ok from the outside but the female threads for the nipple are rusting and corroded and inside it is deteriorating. All the websites and catalogs I have found only have carriers that are much larger and or have features that make it unsuitable (lack of 2inch offset, requires a much thicker wall cavity, has larger mounting brackets) The design seems very small and efficient and has the following details that I would need in a replacement: It fits inside a 2x6 framed wall, supports back to back toilets which are offset by 2 inches from the vertical stack, and the mounting brackets are narrow and not much wider than the toilet mounting bolts. Has anyone seen one of these before and have any information or suggestions on where to look to track one down. Thank you for any help.
