Qjet Carb Code???
 

Restoring my 70 cst 10 400 and discovered the carb is date correct but it shows as belonging to a manual transmission rather than auto. The truck was and remains auto, very original vehicle in every way so I suspect it was born with. Seems to me if the carb were to bo bunk, they would have likely replaced it with something newer.

Code is:

704 0509-Q5

Thoughts?
