Hi Marco, Not quite Montreal, but these guys should be able to do it.: Remanufactured Automotive Parts | Rebuilt | Ontario | John Stuart Power Brake Co. Ltd They have F308 caliper rebuilds listed in their catalog, who knows, maybe they have one in stock and you send them yours as a core. I'm sending them my X 1/9 masters/slave to sleeve and calipers to rebuild this spring. I've heard good things, and it's just a quick UPS shipment away. Myron
