I have a Q-jet carb on my car that by the numbers it is for a 67 car with A.I.R. I had my carb rebuilt maybe 30 years ago and they must of slipped me a service carb in place of rebuilding my original. My car has no pollution stuff on it (never did) and I haven't notice any plug on the carb to connect the pollution hoses. This carb I have my be a combination of my original carb and a different body.
The carb I have is 7037218 BD and the book says I should have 7027202 DB. Before I spend $600.00 on a different carb the question I have is, could someone please tell me what the difference is between the two carbs?
