This drawing from Dr. Mccelland looks reasonable from what the Zapruder and Moorman pics show.
Your analysis of Moorman and Zapruder is way off. There is no dispute that Kennedy's head only had 1 exit wound and in Zapruder, the wound location is obvious.
The actual evidence from a variety of unconnected sources is all corroborated, for instance here's a high res Moorman crop showing the same scalp tear matching this autopsy photo.
