I think it was made for the new frames. The old frame and shells mounted with the little tabs with holes, the shell I bought has no tabs. As for frame being blocked no if you look at the model top to bottom it goes shell, frame, then coupler, the screw goes through the coupler box and into the shell tying them all together. My shell just has nowhere for the screw to go.
