So my 54 Chevy has developed a fuel leak on the carb. The motor in the car is a 57 235 that had been replaced some time back in the 80's. I don't know if the carb on it is from 1957, or 1954. I know the kits are different for each one and I have to order it online so I want to be sure. I attached some pics of the carb in question, and a arrow pointing to where the leak is from. I can find no ID number on the castings. Only Rochester logos. Thanks in advance for any insight.
