I'm not sure what you mean by not a "normal" Comp. Plus shifter. That shifter is marked Hurst Competition Plus on the side of it. It was installed in my Dart new back in 1974 with all the parts just as shown in the picture.
The picture that you posted from Brewers is a B-body shifter set up. A whole different bear. The B-body shifter was mounted way forward on the tranny tail piece. Hence the shorter rods and the longer handle. I'm not saying that the short 7" shifter handle is a A-body one. That was the handle that came with the shifter kit when it was new.
