Edelbrock performer carbs are almost identical to the Carter AFB, and the metering rods, jets, and springs are basically the same.
I have edelbrock metering rods, primary jets, and step up springs in the Carter 9605 (600 manual choke) on my Challenger, works just fine. :-D Carter did offer some different diameter options for the metering rods that you can't get from Edelbrock, but the Edelbrock selection is plenty adequate.
