My parts/ shop manual says the carb should be a 367258r92. The little brass tag on it says it's a 367259r92. From what Google is telling me it's from a farmall 560. I need to either rebuild this one or find one that is supposed to be on it. They look identical from what I can see. Is the carb from the 460 better in any way? Should I rebuild this one or find the one that is supposed to be on it?
