A body inner fenders different after 1974?

The AMD ones are patterned to be a direct fit for '71 and older a-Bodies.

That’s kind of a drag for anyone with a charcoal canister car. The inners with the indent for the charcoal canister fit the earlier cars fine. But if you have a car with a charcoal canister there’s no where to mount it easily if you use inner fenders without the indent. Guess it’s all about the guys with 70/71 cars looking “correct” :rolleyes:
