I know we cannot say never but it seems all originals had that design with the two indents. Later service replacements changed some design characteristics with the two indents being eliminated as a part of. I researched that quite a lot and from everything found or cars reviewed it indicated the expectation would be having the clamp with two indents. And GM products used that style clamp including Corvettes. One thing that can be done is to compare your clamp against a service replacment to see if it matches.
