Is there any numbers on the tag that would identify the year? The tag on the carb on my 67 dart GT convertible(273, 2 barrel, automatic)is blue. the carb could have been replaced, I suppose.
I'm not sure about carburators from 1967. I know for sure that carbs manufactured for 1965 production has the date code stamped on the lower front face on the body just underneath the right front nut and washer holding the carb. I have L4 on my car which is November 1964. I know later cars had the date code on the tag, not on the body. But I'm not sure which year they started with it!
